【Abstract】 Sliding mode controller of variable structure has been gradually applied in the electric drives because of its robust and easy realization. The biggest obstacle for engineering application is chattering resulting from high frequency switching control. The paper firstly analyzes the reason and feature for chattering, when a traditional sliding mode control is used in AC servo system. And then proposes a chattering free robust sliding mode controller, and proves the principle for selecting parameter of the controller. Experiment illustrates that the new controller not only keep the robust of traditional sliding mode control, but also solve the chattering problem.更多还原
