Ac Permanent Magnet Synchronous Motor Servo System Design

Servo system combines the electrical motor theory with modern power electronics technique, sensor techniques, microprocessor techniques and advanced control theory.The dissertation focuses on the design of the system fot permanent magnet synchronous motor servo system based on the infineon XC167CI single chip, and has done some theoretic research as well as experimental research to some key parts.Firstly, the dissertation summarizes the current development of AC servo systems, and understands the significance of the development of AC servo systems, and understands the significance of developing PMSM servo system clearly, then bring forward the content and plain for the study.Secondly, the dissertation introduces how PMSM works and how to control it. It summarizes the principle and implementation of the Field-Oriented Control, adopts the field-weaken based on the smallest port voltage ratio yo extend the range of speed, and designs the control scheme of AC servo control system.Thirdly, an experimental platform of motor control using SVPWM to achieve Field-Oriented Control is designed based on XC167CI in this dissertation, at the same time, do some researching on the design of hardware and software for the system. At the same time, also do some researching on the Electronic Magnetic Interference and Electronic Magnetic Compatibility of the system.Finally, the result of experiment is proved correct and deepened the conclusions drawn from theoretic research.
