Download or read book Linear Electric Machines Drives and MAGLEVs Handbook written by Ion Boldea and published by CRC Press. This book was released on 2023-07-31 with total page 737 pages. Available in PDF, EPUB and Kindle. Book excerpt: Linear motion is richly present in various industries, from direct electric propulsion in urban and interurban people movers on wheels or on magnetic “cushions” (MAGLEVs) to indoor transport of goods (conveyors, etc.), through plunger solenoids (to open hotel doors and as electromagnetic power switches), to compressor drives by linear oscillatory permanent magnet (PM) motors, smart phones integrated microphone and loudspeakers, and controlled vehicles’ suspension, etc. Besides the traditional rotary motor drives with mechanical transmissions, which mean friction limitations (weather dependent) in traction (heavy vehicles), more losses, positioning errors (backlash) in the process, and higher maintenance costs to handle them, linear motion in industry by direct electromagnetic forces is free of friction limitations for traction, free of mechanical transmission, and thus more efficient, with less maintenance cost and fewer positioning errors (backlash). This explains why they are used in so many applications already since the dramatic advancement of power electronics and digital control in the last four decades. Modeling, performance, design, control, and testing of linear electric machines (LEMs) show notable differences with respect to rotary electric motor drives, which warrant a dedicated treatment of these aspects. The Second Edition (First Edition: 2013) concentrates on the above technical aspects of various types of LEMs in close relationship with specific applications via numerical examples of modeling, design, control, and testing, with ample representative results from literature, industry and some of the author’s contributions, such as: Technical field and circuit modeling of linear induction motors in flat configurations for low and high speeds (with and without dynamic end effects) and in tubular configurations short travel design, control and testing Linear synchronous motor (LSM) drives in dc-excited, homopolar, reluctance and superconducting excitation configurations for urban and interurban high-speed vehicles propulsion and integrated propulsion and levitation (in MAGLEVs) modeling, design and control with full-scale numerical examples, with emphasis on lower KWh/passenger/Km at high speeds Flat and tubular linear permanent magnet (PM) synchronous motors (L-PMSMs), mainly destined to industrial indoor transport for automation at high efficiency in clean rooms Linear “flux-modulation” motors— new breed, suitable for very low-speed applications due to higher thrust density Plunger solenoids in various applications including new valve PM actuators with millisecond response time Linear resonant PM oscillatory motors design, control and testing mainly destined to compressors for higher efficiency in compact drives Attraction and repulsive force suspension (levitation) systems for MAGLEVs Active and passive guideway MAGLEVs in urban and superhigh-speed interurban transport at lower Kwh per passenger/km (in lighter vehicles without wheels) The numerous numerical design and control examples (with practical specifications) throughout the 23 chapters of the book allow the reader deep and fast access to a practical but thorough unitary (good for comparisons) methodology in designing and controlling LEMs for various applications.

Available in PDF, EPUB and Kindle. Book excerpt: Despite two decades of massive strides in research and development on control strategies and their subsequent implementation, most books on permanent magnet motor drives still focus primarily on motor design, providing only elementary coverage of control and converters. Addressing that gap with information that has largely been disseminated only in journals and at conferences, Permanent Magnet Synchronous and Brushless DC Motor Drives is a long-awaited comprehensive overview of power electronic converters for permanent magnet synchronous machines and control strategies for variable-speed operation. It introduces machines, power devices, inverters, and control, and addresses modeling, implementation, control strategies, and flux weakening operations, as well as parameter sensitivity, and rotor position sensorless control. Suitable for both industrial and academic audiences, this book also covers the simulation, low cost inverter topologies, and commutation torque ripple of PM brushless DC motor drives. Simulation of the motor drives system is illustrated with MATLAB® codes in the text. This book is divided into three parts—fundamentals of PM synchronous and brushless dc machines, power devices, inverters; PM synchronous motor drives, and brushless dc motor drives. With regard to the power electronics associated with these drive systems, the author: Explores use of the standard three-phase bridge inverter for driving the machine, power factor correction, and inverter control Introduces space vector modulation step by step and contrasts with PWM Details dead time effects in the inverter, and its compensation Discusses new power converter topologies being considered for low-cost drive systems in PM brushless DC motor drives This reference is dedicated exclusively to PM ac machines, with a timely emphasis on control and standard, and low-cost converter topologies. Widely used for teaching at the doctoral level and for industrial audiences both in the U.S. and abroad, it will be a welcome addition to any engineer’s library.

Download or read book Intelligent Adaptive and Sensorless Control of Permanent Magnet Synchronous Linear Motor written by Zheng Li and published by Eliva Press. This book was released on 2022-09-16 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the rapid development of military and aerospace industries, the performance requirements of numerical control equipment are constantly improving. Permanent magnet linear synchronous motor (PMLSM) has the advantages of high speed and high precision. Meanwhile, it overcomes the influence of various factors in the intermediate links such as the screw and gear in the rotating motor. Therefore, PMLSM has very important value in high-precision industrial servo applications that require high-precision linear servo drivers. This book mainly introduces the intelligent vector control strategy and sensorless control strategy of PMLSM. Compared with the traditional control strategy, the intelligent vector control strategy of the motor can better improve the control performance of the motor. In modern motor control systems, many new intelligent vector control strategies have been proposed. This paper focuses on the sliding mode control strategy, model predictive control strategy, adaptive control strategy, active disturbance rejection control strategy and model free control strategy of PMLSM. Relying on the mathematical model of PMLSM, the formula derivation of the above intelligent control strategies is explained in detail, and the system block diagram is drawn to help readers better understand the basic working principle of these intelligent control strategies. In the control system of the motor, in order to achieve better control performance, accurate speed information and mover position information of the PMLSM are required. The traditional collection of speed information and mover position information is realized by adding mechanical sensors, but the addition of mechanical sensors will lead to an increase in the cost of the motor. Meanwhile, the size and weight of the motor will be affected, and there will be some additional interference factors, which will have a certain impact on the control performance of the motor. In order to make the motor get rid of the dependence on mechanical sensors, the sensorless control strategy is introduced into the motor control system, and the position information and speed information of the motor are estimated through a certain control algorithm. At present, the common sensorless control strategies are high-frequency signal injection method and fundamental back EMF observation method. This paper introduces the design of the sliding mode observation method, the observation method based on the model reference adaptive system and the observation method based on the extended Kalman filter algorithm. The above sensorless control strategies are introduced in detail through the corresponding formula derivation and system block diagram.
