Abstract Servo system consists of electrical motor manufacture techniques, power electronics techniques，sensor techniques，microprocessor techniques and modern advanced control theories .With the continuous appearance of new power components and high-performance processors, the application of a variety of AC servo motor is more and more extensive. As the representative of modern electrical motors ， permanent magnet synchronous motor(PMSM) is ideal for advanced servo systems for its potentials of high efficiency，high torque to current ratio，and low inertia .Thus，permanent magnet synchronous motor is widely used in servo control field. The dissertation focuses on the design of system for permanent magnet synchronous motor servo system based on the most advanced DSP chip-TMS320F28335，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 on the basis of comprehensive exposition，and makes a brief introduction on AC permanent magnet synchronous servo system control technology, then bring forward the research and work arrangements for the study. Secondly，an experimental platform using TMS320F28335 as core controller for motor control is designed in this paper, while applying SVPWM to achieve Field-oriented Controlling, of which the main circuit is a typical two level three-phrase AC-DC-AC inverter. IPM(Intelligent Power Module) is used as the main switch of the inverter. the inverter and switching power are supplied by a three-phase Diode bridge rectifier module .At the same time，doing some research on the design of hardware and software for the system. Finally, the software simulation result of above system is obtained, validating and deepening the conclusions drawn from theoretical research.
