Abstract

A new sliding mode control method is presented in this article for AC servo system. Combining fuzzy control and sliding mode control, the chattering of sliding mode control is solved. Introducing an integral element, the stable-state precision is enhanced. The sliding surface designed by means of this method is a time-varied one, which has powerful robustness to parameter variations and external disturbances. Simulation study results show that this method is correct and effective
