Abstract :
This paper introduces the control theory of the permanent magnet synchronous motor (PMSM) and it s mathematic model. Based on this, we design a kind of digital servo system of the permanent magnet synchronous motor based on TMS320F2812.We presented an adaptive fuzzy sliding mode controller of nonlinearity and uncertainty for permanent magnet synchronous motors (PMSM) servo system. This controller made use of fuzzy control to assign compensate according to expert´s experience, and adaptive control to attenuate chattering caused by sliding mode. This method was applied to speed control of the PMSM servo system. Simulation verified the validity and robustness against uncertainties of load disturbance.
