Design And Research Of Permanent Magnet AC Servo System Based On TMS320F28335

The servo system is a product of modern industrial which consis of electrical motor manufacture techniques, power electronics techniqu, sensor techniques, microprocessor techniques and modern advanced control theories.Thanks to it’s excellent control performance,so it has been widely used in various fields.On the other hand,compared with the traditional excitation synchronous motor,permanent magnet synchronous motor exhibits higher efficiency and higher power density.Thus,the permanent magnet synchronous motor have found an increasingly wide application in all fields.This paper focuses on the design of system for permanent magnet synchronous motor servo system based on the TI company C2000 series digitl DSP chip-TMS320F28335, and has done some theoretic research and experimental research to some key parts like vector control and SVPWM modulation.Firstly,the paper makes a comprehensive exposition of the current development and theoy of AC servo systems on the basis of literature,and also makes a brief introduction on AC permanent magnet synchronous servo system control technology. Using the Matlab/Simulink for control systems simulation to verify the theoretical analysis.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,bulit the permanent magner synchronous AC servo system hardware paltform based on TMS320F28335 and designed the field oriented vector control software basedonthe technology of space vector pulse width modulation (SVPWM). Meanwhile,the experiment results were consistent with the theoretical analysis and simulation results, which will be a solid foundation for further studies.
