This book was released on 2013 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document presents implementation of deadbeat-direct torque and flux control (DB-DTFC) for an interior permanent magnet synchronous machine (IPMSM) at voltage- and current- limited condition and robustness evaluation of a DB-DTFC IPMSM drive with respect to parameter variations. When a motor is operated at voltage- and current- limits, a transient torque response becomes slow due to lack of voltage to develop torque changes. Many solutions have been presented and focused on a full utilization of inverter voltage instead of improving transient torque responses. A few methods have addressed optimal solutions to achieve fast torque responses but algorithms are complicated to implement in real time. This research presents development of time optimal and real time suboptimal control algorithms to improve transient torque dynamics of an IPMSM drive at voltage and current limits. Also, loss minimizing stator flux linkage is used during steady state operation to reduce computational complexity of optimization and to operate IPMSM drives at the loss minimizing condition. The voltage- and current- limited operation of IPMSM drives is implemented and evaluated in simulation and in experiment. This research also presents robustness evaluation of DB-DTFC of IPMSM drives with respect to machine parameter variations. For performance comparison, current vector control (CVC), one of the most widely used control methods, is also implemented under identical operating conditions as DB-DTFC. As the metrics to evaluate dynamic performance of DB-DTFC and CVC IPMSM drives, command tracking is used to investigate torque command tracking performance and dynamics stiffness is used to evaluate disturbance rejection performance. In addition, the torque estimation accuracy of DB-DTFC and CVC is investigated with respect to parameter variation. Simulation and experimental results of robustness evaluation of DB-DTFC and CVC are presented.

Available in PDF, EPUB and Kindle. Book excerpt: Permanent magnet synchronous motors (PMSMs) are popular in the electric vehicle industry due to their high-power density, large torque-to-inertia ratio, and high reliability. This book presents an improved field-oriented control (FOC) strategy for PMSMs that utilizes optimal proportional-integral (PI) parameters to achieve robust stability, faster dynamic response, and higher efficiency in the flux-weakening region. The book covers the combined design of a PI current regulator and varying switching frequency pulse-width modulation (PWM), along with an improved linear model predictive control (MPC) strategy. Researchers and graduate students in electrical engineering, systems and control, and electric vehicles will find this book useful. Features: • Implements evolutionary optimization algorithms to improve PMSM performance. • Provides coverage of PMSM control design in the flux-weakening region. • Proposes a modern method of model predictive control to improve the dynamic performance of interior PMSM. • Studies the dynamic performance of two kinds of PMSMs: surface-mounted and interior permanent magnet types. • Includes several case studies and illustrative examples with MATLAB®. This book is aimed at researchers, graduate students, and libraries in electrical engineering with specialization in systems and control and electric vehicles.

Available in PDF, EPUB and Kindle. Book excerpt: The 2010 International Conference on Life System Modeling and Simulation (LSMS 2010) and the 2010 International Conference on Intelligent Computing for Sustainable Energy and Environment (ICSEE 2010) were formed to bring together researchers and practitioners in the fields of life system modeling/simulation and intelligent computing applied to worldwide sustainable energy and environmental applications. A life system is a broad concept, covering both micro and macro components ra- ing from cells, tissues and organs across to organisms and ecological niches. To c- prehend and predict the complex behavior of even a simple life system can be - tremely difficult using conventional approaches. To meet this challenge, a variety of new theories and methodologies have emerged in recent years on life system modeling and simulation. Along with improved understanding of the behavior of biological systems, novel intelligent computing paradigms and techniques have emerged to h- dle complicated real-world problems and applications. In particular, intelligent c- puting approaches have been valuable in the design and development of systems and facilities for achieving sustainable energy and a sustainable environment, the two most challenging issues currently facing humanity. The two LSMS 2010 and ICSEE 2010 conferences served as an important platform for synergizing these two research streams.

Download or read book Deadbeat Flux and Torque Control for Six step Operation of Permanent Magnet Synchronous Machines written by Marc Stephane Petit (Ph.D.) and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a framework for spatial torque control in six-step operation. Six-step operation is desirable for the field-weakening operation of a drive since it maximizes the available voltages and hence minimizes losses and increases the drive's power capability. The proposed framework is based on a deadbeat flux vector controller, which allows control of the flux vector at every sampling instant. This property displays a stark contrast to conventional six-step control, which typically control only the fundamental component of the current. By controlling the instantaneous flux vector and trajectory, the torque can be manipulated to achieve smooth and dynamic torque trajectories without compromising the six-step operation. This work proposes a spatial deadbeat torque controller so that the commanded average torque is achieved after one spatial step, i.e., sixty electrical degrees. This thesis further builds on this control methodology by introducing a spatial z-transform enabling insightful analysis and design of six-step controllers. Command tracking, disturbance rejection, and robustness are evaluated in detail using simulation-based and laboratory experiments on a small-scale 1 kW machine and a full-scale 150 kW automotive test bench. The proposed controller shows significant improvement to state-of-art methods in the speed and smoothness of the torque response. However, the most considerable benefit of this spatial control methodology for six-step is its insightfulness. Since the steady-state and transient trajectories are easy to comprehend and to visualize, more advanced concepts for six-step operation become feasible. Examples of these concepts include instantaneous switching between PWM and six-step operation, observer-based average torque control, and spatial repetitive control.

This book was released on 2020-02-13 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the direct thrust force control (DTFC) of tubular surface-mount linear permanent magnet synchronous motors (linear PMSMs). It presents a detailed account and analysis of several advanced nonlinear control schemes, based on the direct thrust control principle, to achieve a reduction in steady-state ripple in thrust force with faster transient response, and describes their experimental validation. It also provides rigorous details of the dynamic modelling of linear PMSMs from a control system perspective, and demonstrates the superior control performance of the proposed techniques compared to the current state-of-the-art techniques. Lastly, the book proposes and validates a stator flux observer for sensorless speed estimation comprising a linear state observer and an improved sliding mode component.
