The Research Of Permanent Magnet Synchronous Motor Servo System Based On DSP

At present, AC drive has become the fundamental mode in the drive field. With the development of the electrical motor theories, modern power electronics techniques, microprocessor techniques (DSP) and advanced control theories, the application of AC servo technology is more and more extensive. As a result of its outstanding control performance, Permanent Magnet Synchronous Motor (PMSM)is applied more and more in AC servo system. Therefore, studying Permanent Magnet Synchronous Motor servo system based on the DSP is quite significant.AC motor model is a high order, coupling, nonlinear system. The Vector Control has been proposed to decouple PMSM model, constituting the speed regulation system with good performance; In order to realize the precise position control, the repetitive control has been proposed for position servo system.This thesis first introduces the general development situation of servo system of PMSM. Then not only the mathematic model, operation principle of PMSM and the basic theory of Vector Control for PMSM are all illuminated; but also the theory of Repetitive Control and position servo system based on Repetitive Control are analyzed. That is a good...
