Available in PDF, EPUB and Kindle. Book excerpt: For higher energy efficiency and greater motion control flexibility, inverters are used to drive electric motors. High-performance operation of motor drives requires complicated control algorithms and corresponding motor parameter information. Nonetheless, the users may not have the required skills or tools to obtain accurate motor data for high-performance control. Therefore, it is necessary for commercial motor drives to have highly accurate self-commissioning capability. The motor drive parameters obtained by self-commissioning are essential to design the current and speed controllers; high-frequency signal injection based sensorless control, observer-based sensorless control, and energy efficiency improvement schemes such as maximum torque per ampere (MTPA) control. Yet, established self-commissioning methods are not mature enough to provide self-sufficient, robust, and complete solution and also to fully cover newly emerging motor types such as interior permanent-magnet synchronous motors. In order to improve them, the dissertation focuses on a comprehensive study on the end-to-end selfcommissioning of general-purpose industrial sensorless ac motor drives. The dissertation targets full coverage of all motor drive parameters in a self-sufficient way through step-by-step estimation of the relevant parameters. The proposed parameter estimation methods are applicable to all AC motor types whenever the motor nature allows so. First of all, a novel method for spatial inductance map identification is proposed to estimate relevant inductance values which is used to tune the current controller. This method uses open loop voltage injection with automatic selection of injection amplitude and frequency and does not need rotor position information. After current-loop auto-tuning, a precise and robust method for initial rotor position is presented for synchronous motors. Later, estimation methods for stator resistance and saturated inductances are provided for all AC motors. Also, the nature of induction motor introduces unique difficulties in the standstill estimation of magnetizing inductance and rotor resistance. Existing traditional methods of low-frequency current injection and flux integration are not successful enough to provide robust results that can be replicated in many different motorinverter pairs. A simple novel method that makes use of the redundancy of resistive drops during dc-magnetization of the motor is presented to solve to these difficulties. Upon finishing stationary tests, rotational test is required for the estimation of mechanical parameters. Inertia estimation and consequent speed-loop auto-tuning has some challenges such as automatic test torque selection satisfying most of the practical conditions with varying mechanical inertia and loads, creating controlled speed oscillations, and robust signal detection during the test. This dissertation proposes novel solutions to these. Overall, this dissertation proposes an end-to-end, self-sufficient, and robust solution for self-commissioning of sensorless industrial AC drives.

Available in PDF, EPUB and Kindle. Book excerpt: Alternating current (AC) induction and synchronous machines are frequently used in variable speed drives with applications ranging from computer peripherals, robotics, and machine tools to railway traction, ship propulsion, and rolling mills. The notable impact of vector control of AC drives on most traditional and new technologies, the multitude of practical configurations proposed, and the absence of books treating this subject as a whole with a unified approach were the driving forces behind the creation of this book. Vector Control of AC Drives examines the remarkable progress achieved worldwide in vector control from its introduction in 1969 to the current technology. The book unifies the treatment of vector control of induction and synchronous motor drives using the concepts of general flux orientation and the feed-forward (indirect) and feedback (direct) voltage and current vector control. The concept of torque vector control is also introduced and applied to all AC motors. AC models for drive applications developed in complex variables (space phasors), both for induction and synchronous motors, are used throughout the book. Numerous practical implementations of vector control are described in considerable detail, followed by representative digital simulations and test results taken from the recent literature. Vector Control of AC Drives will be a welcome addition to the reference collections of electrical and mechanical engineers involved with machine and system design.

Available in PDF, EPUB and Kindle. Book excerpt: Variable speed is one of the important requirements in most of the electric drives. Earlier dc motors were the only drives that were used in industries requiring - eration over a wide range of speed with step less variation, or requiring fine ac- racy of speed control. Such drives are known as high performance drives. AC - tors because of being highly coupled non-linear devices can not provide fast dynamic response with normal controls. However, recently, because of ready availability of power electronic devices, and digital signal processors ac motors are beginning to be used for high performance drives. Field oriented control or vector control has made a fundamental change with regard to dynamic perfo- ance of ac machines. Vector control makes it possible to control induction or s- chronous motor in a manner similar to control scheme used for the separately - cited dc motor. Recent advances in artificial intelligence techniques have also contributed in the improvement in performance of electric drives. This book presents a comprehensive view of high performance ac drives. It may be considered as both a text book for graduate students and as an up-to-date monograph. It may also be used by R & D professionals involved in the impro- ment of performance of drives in the industries. The book will also be beneficial to the researchers pursuing work on sensorless and direct torque control of electric drives as up-to date references in these topics are provided.

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.
