Available in PDF, EPUB and Kindle. Book excerpt: Induction motors are the most important workhorses in industry. They are mostly used as constant-speed drives when fed from a voltage source of fixed frequency. Advent of advanced power electronic converters and powerful digital signal processors, however, has made possible the development of high performance, adjustable speed AC motor drives. This book aims to explore new areas of induction motor control based on artificial intelligence (AI) techniques in order to make the controller less sensitive to parameter changes. Selected AI techniques are applied for different induction motor control strategies. The book presents a practical computer simulation model of the induction motor that could be used for studying various induction motor drive operations. The control strategies explored include expert-system-based acceleration control, hybrid-fuzzy/PI two-stage control, neural-network-based direct self control, and genetic algorithm based extended Kalman filter for rotor speed estimation. There are also chapters on neural-network-based parameter estimation, genetic-algorithm-based optimized random PWM strategy, and experimental investigations. A chapter is provided as a primer for readers to get started with simulation studies on various AI techniques.

Book Synopsis Noise Optimized Control of an Electrical Drive with Induction Machine by : Wolfgang Bischof
Download or read book Noise Optimized Control of an Electrical Drive with Induction Machine written by Wolfgang Bischof and published by Cuvillier Verlag. This book was released on 2019-08-07 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work proposes methods for modeling the acoustic behavior of induction machines as well as optimization approaches for the control of the acoustic behavior. The aim of this work is to simplify and improve the quality of the acoustic modeling of induction machines and to show possible optimization measures in order to make the application and its understanding accessible to a broader group of users. In this work, approaches for the efficient modeling of harmonic phenomena in the electromagnetics of induction machines are shown and analyzed. This work focuses on the development of efficient geometric models for the calculation of electromagnetics of induction machines, which are substantially based on analytical equations and are used in an extended simulation via numerical methods. Subsequently, a method for the acoustic calculation of the vibrations resulting from the electromagnetic force excitation on the surface of the housing of the electrical machine is presented. The approach for the calculation of the surface vibrations is based on the system simulation and the vibration synthesis approach. The presented method offers the possibility to present extensive and realistic models and can therefore contribute to the optimized design of induction machines and many other types of electric drive systems. The procedure consists of a two-stage process, whereby a distinction is made between an offline calculation, as a prediction for model parametrization and for the calculation of the electromagnetic behavior as well as an online calculation, which includes the actual acoustic calculation. Based on this efficient calculation method, control and sensor influences as well as spatial harmonics and inverter switching frequency orders can be analyzed and optimized. In addition, two methods are presented, which refer exclusively to the changes of the software and their parametrization of the electric drive system. On the one hand, this work presents a procedure which improves the acoustic behavior by changing the operating point at constant torque and speed of the electric drive. Another method describes the injection of voltage pulses to generate harmonic current oscillations, which counteract with the excitation of occurring vibrations and thus contribute to the reduction and optimization of the acoustic behavior of the induction machine and thus of the electric drive train. Underlining the results of the presented methods, the results of the simulation models are proposed and compared to measurements.
Book Synopsis Dynamics and Control of Electrical Drives by : Wach Piotr
Download or read book Dynamics and Control of Electrical Drives written by Wach Piotr and published by Springer Science & Business Media. This book was released on 2011-04-28 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamics is a science concerned with movement and changes. In the most general approach it relates to life processes as well as behavior in nature in rest. It governs small particles, technical objects, conversion of matter and materials but also concerns people, groups of people in their individual and, in particular, social dimension. In dynamics we always have to do with causes or stimuli for motion, the rules of reaction or behavior and its result in the form of trajectory of changes. This book is devoted to dynamics of a wide class of specific but very important objects such as electromechanical systems. This is a very rigorous discipline and has a long tradition, as its theoretical bases were formulated in the first half of the XIX century by d’ Alembert, Lagrange, Hamilton, Maxwell and other prominent scientists, but their crucial results were based on previous pioneering research of others such as Copernicus, Galileo, Newton... This book in its theoretical foundations is based on the principle of least action which governs classical as well as relativistic mechanics and electromagnetism and leads to Lagrange’s equations which are applied in the book as universal method to construct equations of motion of electromechanical systems. It gives common and coherent grounds to formulate mathematical models for all lumped parameters’ electromechanical systems, which are vital in our contemporary industry and civilized everyday life. From these remarks it seems that the book is general and theoretical but in fact it is a very practical one concerning modern electrical drives in a broad sense, including electromechanical energy conversion, induction motor drives, brushless DC drives with a permanent magnet excitation and switched reluctance machines (SRM). And of course their control, which means shaping of their trajectories of motion using modern tools, their designed autonomy in keeping a track according to our programmed expectations. The problems presented in the book are widely illustrated by characteristics, trajectories, dynamic courses all computed by use of developed simulation models throughout the book. There are some classical subjects and the history of the discipline is discussed but finally all modern tools and means are presented and applied. More detailed descriptions follow in abstracts for the particular chapters. The author hopes kind readers will enjoy and profit from reading this book.

Book Synopsis Noise of Polyphase Electric Motors by : Jacek F. Gieras
Download or read book Noise of Polyphase Electric Motors written by Jacek F. Gieras and published by CRC Press. This book was released on 2018-10-03 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Controlling the level of noise in electrical motors is critical to overall system performance. However, predicting noise of an electrical motor is more difficult and less accurate than for other characteristics such as torque-speed. Recent advances have produced powerful computational methods for noise prediction, and Noise of Polyphase Electric Motors is the first book to collect these advances in a single source. It is also the first to include noise prediction for permanent magnet (PM) synchronous motors. Complete coverage of all aspects of electromagnetic, structural, and vibro-acoustic noise makes this a uniquely comprehensive reference. The authors begin with the basic principles of noise generation and radiation, magnetic field and radial forces, torque pulsations, acoustic calculations, as well as noise and vibration of mechanical and acoustic origin. Moving to applications, the book examines in detail stator system vibration analysis including the use of finite element method (FEM) modal analysis; FEM for radial pressure and structural modeling; boundary element methods (BEM) for acoustic radiation; statistical energy analysis (SEA); instrumentation including technologies, procedures, and standards; and both passive and active methods for control of noise and vibration. Noise of Polyphase Electric Motors gathers the fundamental concepts along with all of the analytical, numerical, and statistical methods into a unified reference. It supplies all of the tools necessary to improve the noise performance of electrical motors at the design stage.

Book Synopsis Control of Electrical Drives by : Werner Leonhard
Download or read book Control of Electrical Drives written by Werner Leonhard and published by Springer Science & Business Media. This book was released on 2001-08-10 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrical drives play an important role as electromechanical energy convert ers in transportation, material handling and most production processes. The ease of controlling electrical drives is an important aspect for meeting the in creasing demands by the user with respect to flexibility and precision, caused by technological progress in industry as well as the need for energy conser vation. At the same time, the control of electrical drives has provided strong incentives to control engineering in general, leading to the development of new control structures and their introduction to other areas of control. This is due to the stringent operating conditions and widely varying specifications - a drive may alternately require control of torque, acceleration, speed or position - and the fact that most electric drives have - in contrast to chem ical or thermal processes - well defined structures and consistent dynamic characteristics. During the last years the field of controlled electrical drives has undergone rapid expansion due mainly to the advances of semiconductors in the form of power electronics as well as analogue and digital signal electronics, eventu ally culminating in microelectronics and microprocessors. The introduction of electronically switched solid-state power converters has renewed the search for adjustable speed AC motor drives, not subject to the limitations of the mechanical commutator of DC drives which dominated the field for a century.

Available in PDF, EPUB and Kindle. Book excerpt: Electrical drives lie at the heart of most industrial processes and make a major contribution to the comfort and high quality products we all take for granted. They provide the controller power needed at all levels, from megawatts in cement production to milliwatts in wrist watches. Other examples are legion, from the domestic kitchen to public utilities. The modern electrical drive is a complex item, comprising a controller, a static converter and an electrical motor. Some can be programmed by the user. Some can communicate with other drives. Semiconductor switches have improved, intelligent power modules have been introduced, all of which means that control techniques can be used now that were unimaginable a decade ago. Nor has the motor side stood still: high-energy permanent magnets, semiconductor switched reluctance motors, silicon micromotor technology, and soft magnetic materials produced by powder technology are all revolutionising the industry. But the electric drive is an enabling technology, so the revolution is rippling throughout the whole of industry.

Book Synopsis Control and Nonlinear Dynamics on Energy Conversion Systems by : Herbert Ho-Ching Iu
Download or read book Control and Nonlinear Dynamics on Energy Conversion Systems written by Herbert Ho-Ching Iu and published by MDPI. This book was released on 2019-07-01 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ever-increasing need for higher efficiency, smaller size, and lower cost make the analysis, understanding, and design of energy conversion systems extremely important, interesting, and even imperative. One of the most neglected features in the study of such systems is the effect of the inherent nonlinearities on the stability of the system. Due to these nonlinearities, these devices may exhibit undesirable and complex dynamics, which are the focus of many researchers. Even though a lot of research has taken place in this area during the last 20 years, it is still an active research topic for mainstream power engineers. This research has demonstrated that these systems can become unstable with a direct result in increased losses, extra subharmonics, and even uncontrollability/unobservability. The detailed study of these systems can help in the design of smaller, lighter, and less expensive converters that are particularly important in emerging areas of research like electric vehicles, smart grids, renewable energy sources, and others. The aim of this Special Issue is to cover control and nonlinear aspects of instabilities in different energy conversion systems: theoretical, analysis modelling, and practical solutions for such emerging applications. In this Special Issue, we present novel research works in different areas of the control and nonlinear dynamics of energy conversion systems.
Book Synopsis Practical Control of Electric Machines for EV/HEVs by : Shuiwen Shen
Download or read book Practical Control of Electric Machines for EV/HEVs written by Shuiwen Shen and published by Springer Nature. This book was released on 2023-09-01 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Upon the ongoing profound revolution in the automotive industry, this book is primarily intended to give guidance on the practical design of traction motor control for pure electric vehicles (EVs) and hybrid electric vehicles (HEVs). An overview of the state-of-the-art motor types is provided to help understanding the background of automotive motor drives and the EV/HEV motor control specifications. Using AC induction motor control as a benchmark example, it addresses the motor control techniques by means of design, analysis, examples with MATLAB scripts wherever applicable, and practical control software architecture diagrams. In particular, an extensive analysis and discussion are made on the widely used vector control method together with multiple optimization schemes. As such, it gives coverage of the electric traction control including dynamics, efficiency, and the high-speed power capability, taking into account the constraints of vehicle configuration and requirements. The vector control and optimization strategies presented in this book can be ported across to other AC motor types without losing much generality. This book tries to bridge the gap between theory and practicality. Beginning with basic motor theory and completing the motor control design by introducing voltage source inverter (VSI) pulse width modulation (PWM) techniques, it helps the reader take a step-by-step approach from understanding fundamental motor characteristics through to practical design of in-depth motor control strategies.
Book Synopsis PID Controller Tuning Using the Magnitude Optimum Criterion by : Konstantinos G. Papadopoulos
Download or read book PID Controller Tuning Using the Magnitude Optimum Criterion written by Konstantinos G. Papadopoulos and published by Springer. This book was released on 2014-11-01 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: An instructive reference that will help control researchers and engineers, interested in a variety of industrial processes, to take advantage of a powerful tuning method for the ever-popular PID control paradigm. This monograph presents explicit PID tuning rules for linear control loops regardless of process complexity. It shows the reader how such loops achieve zero steady-position, velocity, and acceleration errors and are thus able to track fast reference signals. The theoretical development takes place in the frequency domain by introducing a general-transfer-function-known process model and by exploiting the principle of the magnitude optimum criterion. It is paralleled by the presentation of real industrial control loops used in electric motor drives. The application of the proposed tuning rules to a large class of processes shows that irrespective of the complexity of the controlled process the shape of the step and frequency response of the control loop exhibits a specific performance. This specific performance, along with the PID explicit solution, formulates the basis for developing an automatic tuning method for the PID controller parameters which is a problem often met in many industry applications—temperature, pH, and humidity control, ratio control in product blending, and boiler-drum level control, for example. The process of the model is considered unknown and controller parameters are tuned automatically such that the aforementioned performance is achieved. The potential both for the explicit tuning rules and the automatic tuning method is demonstrated using several examples for benchmark process models recurring frequently in many industry applications.

Book Synopsis Sensorless AC Electric Motor Control by : Alain Glumineau
Download or read book Sensorless AC Electric Motor Control written by Alain Glumineau and published by Springer. This book was released on 2015-03-16 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph shows the reader how to avoid the burdens of sensor cost, reduced internal physical space, and system complexity in the control of AC motors. Many applications fields—electric vehicles, wind- and wave-energy converters and robotics, among them—will benefit. Sensorless AC Electric Motor Control describes the elimination of physical sensors and their replacement with observers, i.e., software sensors. Robustness is introduced to overcome problems associated with the unavoidable imperfection of knowledge of machine parameters—resistance, inertia, and so on—encountered in real systems. The details of a large number of speed- and/or position-sensorless ideas for different types of permanent-magnet synchronous motors and induction motors are presented along with several novel observer designs for electrical machines. Control strategies are developed using high-order, sliding-mode and quasi-continuous-sliding-mode techniques and two types of observer–controller schemes based on backstepping and sliding-mode techniques are described. Experimental results validate the performance of these observer and controller configurations with test trajectories of significance in difficult sensorless-AC-machine problems. Control engineers working with AC motors in a variety of industrial environments will find the space-and-cost-saving ideas detailed in Sensorless AC Electric Motor Control of much interest. Academic researchers and graduate students from electrical, mechanical and control-engineering backgrounds will be able to see how advanced theoretical control can be applied in meaningful real systems.
