Fuzzy sliding mode controller based on trending law for electric actuator

Fuzzy sliding mode controller based on trending law for electric actuator is proposed in this paper. The sliding mode is used to enhance the robustness of the system, the trending law is used to improve the system dynamic characteristics of reaching the sliding surface, and the fuzzy tuning schemes are employed to reduce the chattering problem around the sliding surface. The integral sliding mode controller with exponential reaching law was developed. And the parameters of the exponential trending law were configured by fuzzy control rule. The method is applied to the control of an electric actuator. And the results of the simulation verify the validity of the proposed approaches.
