摘要：

This paper proposes a variable-structured robust controller whose structure is continuously changed by fuzzy logic such that the controller makes the system respond quickly if the error e is large or its rate e is large and vice versa in order to obtain a robust controller that is insensitive to both the plant noise and the observation noise. Then it is applied practically to speed control for an induction servomotor. Experiments show that the proposed controller is superior to both a sliding mode controller and a PID controller. The paper includes the stability analysis of the overall system and the design procedure by using Lyapunov's method.
