Book Synopsis Modeling and Control of Switched Reluctance Machines for Four-quadrant Operation by : Sandeep Narla
Download or read book Modeling and Control of Switched Reluctance Machines for Four-quadrant Operation written by Sandeep Narla and published by . This book was released on 2010 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: The switched reluctance machine (SRM) is receiving renewed attention as a viable candidate for various adjustable speed and high torque applications such as in the automotive, traction and aerospace industries. The unique feature of a SRM is its relatively simple mechanical structure; the rotor does not carry any windings, commutators or permanent magnets. The maintenance free usage makes it a good choice over other DC or AC drives. The software modeling and hardware testing of SRM, for four-quadrant operation, and the development of an optimum commutation angle controller for low output current ripple, and efficient battery charging using the switched reluctance generator (SRG) is presented in this thesis. Two different SRM models are simulated for controller development. One of the models is the geometry based machine model by A. Radun, which is used to develop the operation logic for four-quadrant control of a three-phase 12/8 pole SRM. The second model is based on torque and flux data generated through finite element analysis using the software Flux2D for the three-phase 12/8 SRM. Simulation results obtained from the models were used to develop a control strategy to adapt the commutation angles in real-time for efficient battery charging with minimized current ripple. Two digital controllers namely, the turn-on angle controller for regulating the charging current and the turn-off angle controller for minimizing current ripple (adjusting algorithm) are developed to deliver the desired output power. The controller algorithm is implemented in a TI digital signal processor (DSP) for real-time controls. The SRM power and control hardware cards are integrated into a complete SRM drive system for experimental verification. The experimentally obtained commutation angles are compared with the data table generated from simulation results.

Available in PDF, EPUB and Kindle. Book excerpt: In the last years, the switched reluctance machines (SRMs) have been the subject of significant developments. SRMs are gaining much interest because of their simplicity in structures, high-output power, high starting torque, wide speed range, rugged and robust construction, reliability, and low manufacturing costs, which make these machines viable for many applications. SRMs include machines of different structures whose common property is the significant variation in the shape of the air gap during rotation. The use of advanced control technologies makes possible the integration of the mechanical and electrical conversion systems in their optimal mode of operation. Different strategies of control can be applied to SRMs, depending on their mode of functioning and the purpose of their applications. The goal of this book is to present recent works on concept, control, and applications in switched reluctance machines.
Book Synopsis Switched Reluctance Motor Drives by : R. Krishnan
Download or read book Switched Reluctance Motor Drives written by R. Krishnan and published by CRC Press. This book was released on 2017-12-19 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: The switched reluctance machine (SRM) is the least expensive electrical machine to produce, yet one of the most reliable. As such, research has blossomed during the last decade, and the SRM and variable drive systems using SRMs are receiving considerable attention from industry. Because they require a power electronic converter and controller to function, however, successful realization of an SRM variable drive system demands an understanding of the converter and controller subsystems and their integration with the machine. Switched Reluctance Motor Drives provides that understanding. It presents a unified view of the machine and its drive system from all of its system and subsystem aspects. With a careful balance of theory and implementation, the author develops the analysis and design of SRMs from first principles, introduces a wide variety of power converters available for driving the SRM, and systematically presents both low- and high-performance controllers. The book includes an in-depth study of acoustic noise and its minimization along with application examples that include comparisons between ac and dc drives and SRM drive. The result is the first book that provides a state-of-the-art knowledge of SRMs, power converters, and their use with both sensor-based and sensorless controllers. Switched Reluctance Motor Drives enables both students and engineers to learn all aspects of SRM drive systems and appreciate the interdependence of the various subsystems in performance optimization.

Book Synopsis Reliability Based Multi-objective Design Optimization for Switched Reluctance Machines by : Lavanya Vadamodala
Download or read book Reliability Based Multi-objective Design Optimization for Switched Reluctance Machines written by Lavanya Vadamodala and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, a numerical model is developed for estimating the reliability of a Switched Reluctance Machine (SRM), and is then used in its design optimization. SRM design optimization is performed using the multi-objective surrogate optimization method. The multi-objective surrogate optimization method is chosen because of its ability to find a global solution within a given number of function evaluations. In this study, optimization considers reliability as one of the objectives or constraints to obtain an optimal design with high reliability. The optimum design should operate for the target lifetime (20000 hours) before maintenance or complete replacement. Since optimization using 2D FEA is slow, a modified analytical model is developed to more quickly obtain a suitable design. This model predicts flux linkage and torque for a given phase current and rotor position with minimum error. Tapering in the stator and rotor poles is introduced in addition to traditional rectangular poles to reduce the error in predicting flux linkage and torque at unaligned and partially aligned positions. An improved BH curve model with a knee adjustment factor is used to predict the magnetic characteristics of steel used in the machine. Assumptions and detailed derivation of models to estimate flux linkage, co-energy, and torque are included. Reliability is defined as the probability of a component or system operating for a given time. The probability of a component to operate is calculated based on its failure rate. The failure rate of the machine is obtained as the combination of the machine's base failure rate and the failure rate of the windings, rotor, and shaft. The reliability of the machine is obtained using state transition diagrams associated with the Markov model under normal and fault conditions. Along with the machine's reliability, Mean Time to Failure (MTTF) is also predicted for all operating conditions. Using the developed analytical and reliability models for SRM, optimization is performed in two stages. In first stage, sensitivity analysis is performed using the Taguchi methodology, where the sensitivity of objectives to change in each independent variable is calculated. Based on this, sensitive and non-sensitive variables are identified. In second stage, optimization using the multi-objective surrogate optimization method is carried out. Both single and double-level optimization methods are performed to look at the advantages and disadvantages of the optimization methods and optimum designs obtained based on the number of iterations and design performance. In this thesis, the reliability models are developed for a 32 kW SRM. This machine's target application is Front End Motor Generator (FEMG) to drive engine accessories in an electric truck. The optimum design obtained for the 32 kW SRM is verified with Finite Element Analysis (FEA), and the prototype is built. The performance of the machine is validated using experimental results from the testing of the prototype. The failure factor and MTTF are calculated using measurements. It was found that there is good agreement between predictions from simulation and experimental measurements.
