Download or read book High Performance AC Drives written by Mukhtar Ahmad and published by Springer Science & Business Media. This book was released on 2010-09-08 with total page 195 pages. 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.
Download or read book Fault Tolerant Control of Multiphase Induction Motor Drives written by Amr Al Ashi and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although three-phase electric machines play a great role in almost all industrial applications, they still have limitations to cover high power requirements needed for traction, propulsion and other high power applications. Nowadays, multiphase electric machines with high output power can solve this problem. A multiphase machine does not only provide higher torque per unit volume, but it also provides higher degrees of reliability due to fault-tolerant capability provided by the additional degrees of freedom. This is a crucial issue for safety-critical applications, e.g., electric ship propulsion, air crafts and aerospace applications. This work presents in details a seven-phase induction motor drive based on indirect field oriented control technique with fault-tolerant controller, which allows the motor to ride-through the fault period caused by a phase loss. Using MATLAB simulation, the problem of "phase disconnection" is addressed and two fault-tolerant control strategies are proposed to compensate its effect.

Download or read book Multi phase Machine Drives and Controls written by Zhouzhou Wang and published by . This book was released on 2024 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiphase machines are gaining attention in academia and industry for their excellent fault-tolerance and flexibility in operation. Bearingless machines are one type of multiphase machine that manipulate magnetic force to support the rotor, thereby, eliminating the use of bearings. Modular motor drives (MMDs) are the ones that are excellent for fault-tolerance. First, this research focuses on developing cost-effective, high-performance industrial-scale bearingless drives using combined windings. The research compares four drive configurations for two degrees of freedom (DOF) bearingless machines, with the middle-point current injection (MCI) drive emerging as the most cost-effective solution for high torque applications. Additionally, the study proposes reduced-component configurations for 4-DOF twin bearingless machines, demonstrating a 25% reduction in inverters and supporting components while maintaining effective levitation and control in experimental results. Electric Propulsion Units (EPUs) demand paramount reliability and power density to rival conventional jet engines. Permanent Magnet (PM) Modular Motor Drives (MMDs) stand out as promising EPU candidates due to their excellent reliability, power density, and fault-tolerance. The second part of the research focuses on distributed MMD controls. To facilitate strengths of MMDs, distributed controls are promising solution to improve the systems reliability. The deadbeat direct torque and flux control (DB-DTFC) becomes appealing for MMD controls for its extremely fast dynamic response and extraordinary voltage limit handling. This research proposed the baseline and improved distributed current and flux observers and distributed DB-DTFC for MMDs. The existing electromagnetic asymmetries in MMDs introduce negative sequence components, which degrade the accuracy of the conventional current and flux observers. The proposed current and flux observers are intended to track the fundamental and negative sequence components, including the intra-module asymmetry and inter-module cross-couplings of MMDs, which ensure the precise torque control performance of the distributed DB-DTFC. The simulation and experiments validated the accurate estimation and prediction abilities of the observers and the fast torque tracking responses of the closed-loop DB-DTFC control.

Download or read book Open Phase Fault Operation on Multiphase Induction Motor Drives written by Hugo Guzman and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiphase machines have been recognized in the last few years like an attractive alternative to conventional three-phase ones. This is due to their usefulness in a niche of applications where the reduction in the total power per phase and, mainly, the high overall system reliability and the ability of using the multiphase machine in faulty conditions are required. Electric vehicle and railway traction, all-electric ships, more-electric aircraft or wind power generation systems are examples of up-to-date real applications using multiphase machines, most of them taking advantage of the ability of continuing the operation in faulty conditions. Between the available multiphase machines, symmetrical five-phase induction machines are probably one of the most frequently considered multiphase machines in recent research. However, other multiphase machines have also been used in the last few years due to the development of more powerful microprocessors. This chapter analyzes the behavior of generic n-phase machines (being n any odd number higher than 3) in faulty operation (considering the most common faulty operation, id est the open-phase fault). The obtained results will be then particularized to the 5-phase case, where some simulation and experimental results will be presented to show the behavior of the entire system in healthy and faulty conditions. The chapter will be organized as follows: First, the different faults in a multiphase machine are analyzed. Fault conditions are detailed and explained, and the interest of a multiphase machine in the management of faults is stated. The effect of the open-phase fault operation in the machine model is then studied. A generic n-phase machine is considered, being n any odd number greater than three. The analysis is afterwards particularized to the 5-phase machine, where the open-phase fault condition is managed using different control methods and the obtained results are compared. Finally, the conclusions are presented in the last section of the chapter.
Download or read book Advanced Electrical Drives written by Rik W. De Doncker and published by Springer Nature. This book was released on 2020-08-21 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a unique approach to derive model-based torque controllers for all types of Lorentz force machines, i.e. DC, synchronous and induction machines. The rotating transformer model forms the basis for the generalized modeling approach of rotating field machines, which leads to the development of universal field-oriented control algorithms. Contrary to this, direct torque control algorithms, using observer-based methods, are developed for switched reluctance machines. Tutorials are included at the end of each chapter, and the reader is encouraged to execute these tutorials in order to gain familiarity with the dynamic behavior of drive systems. This updated edition uses PLECS® simulation and vector processing tools that were specifically adopted for the purpose of these hands-on tutorials. Hence, Advanced Electrical Drives encourages “learning by doing” and the experienced drive specialist may find the simulation tools useful to design high-performance torque controllers. Although it is a powerful reference in its own right, when used in conjunction with the companion texts Fundamentals of Electrical Drives and Applied Control of Electrical Drives, this book provides a uniquely comprehensive reference set that takes readers all the way from understanding the basics of how electrical drives work, to deep familiarity with advanced features and models, to a mastery of applying the concepts to actual hardware in practice.

Download or read book Multiphase Permanent Magnet Machines written by Kai Wang and published by Wiley-IEEE Press. This book was released on 2024-02-20 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The adoption of advanced technical solutions to match the requirements of energy efficiency is becoming increasingly essential, promoting a gradual transformation in the field of mechanical actuators and shifting the attention to more electric and efficient systems. The main driving force is the need for new solutions in specific application areas such as railway traction, electric and hybrid vehicle applications, ‘more-electric’ aircraft, electric ship propulsion, and general high-power applications. Multi-phase motor drives are gaining a growing interest because they permit a boost in torque and power density, allowing the design of very compact high efficiency drives with positive reliability outcomes. Traditional solutions for electric drive/generation systems, based on three-phase machinery, are not necessarily the best solutions, however. Moreover, since the electric machine is either typically decoupled from the mains, or the actual power system is an autonomous one, the number of phases of the machine does not have to be limited to only three. The resultant ‘multiphase machines’ offer numerous potential advantages over their three-phase counterparts. This book aims at presenting the new research results concerning multiphase machines and drives, AC multiphase power converters and their applications, as related to ‘more-electric’ transport.
