Abstract:

This paper discusses a permanent magnet synchronous motor (PMSM) variable frequency drive (VFD) system developed for an all-terrain Wifi-HaLow connected (802.11ah, 900 MHz) modular electric vehicle that competed in the Mars University Rover Challenge (URC). The quadrature axis flux linkage for each motor was estimated using on-board voltage and current measurements. A synchronous control algorithm tracked the electromagnetic operating parameters, which are highly dependent on variations in motor construction and load conditions. A feed-forward model-driven observer solution calculated flux lin

Abstract:

Use of permanent magnets made of rare earth materials such as samarium cobalt and neodymium-boron-iron in Permanent Magnet Synchronous Motor (PMSM) drives has resulted in high flux density and improved performance of the drive. Field Oriented Control (FOC) has become one of the most popular speed and torque control techniques for AC motors. In PMSM drive detection/computation of rotor position is crucial for ensuring high performance during FOC. Rotor position is often sensed by incremental encoders or resolvers. The use of positon sensors in motor speed control increases the cost, size,

碩士<br>國立勤益科技大學<br>電機工程系<br>98<br>In this thesis the sensorless permanent magnet synchronous motor drive by using high frequency signal injection is presented. Today, reducing carbon emission and energy is the goal for world development. Permanent magnet synchronous motor（PMSM）compare with other type motors has the merits for low noise, high power density, high efficiency, and less maintenance, which has been widely used in industry and household appliances. Furthermore, the high power semiconductor devices is continued development, the exploitation of micro processing technology which has abil

碩士<br>國立清華大學<br>電機工程學系<br>98<br>This thesis develops a motor drive system for condensing unit applications. The system consists of a position sensorless sinewave excited interior permanent-magnet synchronous motor (IPMSM) driven compressor, a square-wave excited surface mounted PMSM (SPMSM) driven fan, and a single-phase boost-type switch mode rectifier (SMR) front end to establish their common DC-link voltage from utility with satisfactory line drawn power quality. All the constituted power stages are fully digitally controlled in a common digital signal processor (DSP). For the compresso

碩士<br>國立臺灣科技大學<br>電機工程系<br>97<br>This thesis investigates performance improvement of micro-permanent magnet synchronous motor drive systems. Two estimators, which include a state estimator and a rotor position/speed estimator, are proposed. First, the state estimator has been designed to improve the low speed performance of a micro permanent magnet synchronous motor drive system due to its low resolution encoder. Next, a novel position/speed estimator has been designed, which can obtain the position/speed by detecting the zero-current crossing signals. The position/speed estimator combines a z

碩士<br>國立臺灣科技大學<br>電機工程系<br>91<br>This thesis presents the analysis and implementation of a unity power factor, low current harmonics drive for permanent-magnet synchronous motors. In this system, a three-level, three-switch boost converter is used to substitute a full-bridge rectifier circuit. In order to reduce the switching loss, a new switching algorithm is proposed. As to the drive of permanent-magnet synchronous motors, the rotor-flux-oriented vector control algorithm is implemented to regulate the rotor speed stably. Besides, an inverter using sinusoidal-pulse-width-modulation technique

One is concerned with the design of permanent-magnet synchronous motor (PMSM), where Maxwell 2D produced by Ansoft company is used to obtain the optimum design with cost reduction as well as the assurance of motor performance. The other is the design of ac-dc-ac power converter which uses three-phase full-controlled full-bridge type power factor corrector in place of traditional diode rectifiers to drive the designed PMSM. The proposed control strategy not only reduces harmonic current and improves power factor in the power

碩士<br>國立中正大學<br>電機工程研究所<br>103<br>This thesis is mainly about implementation of a motor driver for permanent-magnet synchronous motor. Proportional-integral (PI) control is mainly applied to motor drive control. If the capability of load variation rejection is good, the tracking ability might become poor. Therefore, this study adopts the T-S Fuzzy control method, which can design a controller with good tracking ability and load variation regulation for the system. First, the model of permanent magnet synchronous motors is introduced. Second, the tracking control strategy of permanent magnet sy

博士<br>國立臺灣科技大學<br>電機工程系<br>104<br>This dissertation proposes a dual-permanent-magnect-synchronous- motor drive system to increase its efficiency and to extend its constant-torque operation speed range. The proposed drive system can be separately operated at a low-speed operation mode and a high-speed operation mode. In the low-speed operation mode, the output torque is shared by the dual motors. A maximum efficiency control is proposed by suitably adjusting the distribution ratio between the two motors, so a maximum efficiency of the whole drive system can be achieved.

碩士<br>明新科技大學<br>電機工程研究所<br>102<br>In the conventional field-weakening control of the surface-mounted permanent -magnet synchronous motor (SMPMSM) drive, there are several drawbacks, which are high copper loss, serious current chattering phenomena, poor current transient response, and sensitivity to the variation of dc-link voltage. Therefore, the aim of this thesis is to propose a integrated SMPMSM drive to improve the above drawbacks. Basically, the major contributions of this thesis can be summarized as follows, First, the proposed integrated SMPMSM drive can obtain two different levels of d
