Output Feedback Based Sliding Mode Control for Fuzzy Systems With Actuator Saturation
In this paper, a novel adaptive sliding mode controller is designed for Takagi Sugeno (T S) fuzzy systems with actuator saturation and system uncertainty. By the delta operator approach, the discrete time nonlinear system is described by a T S fuzzy model with unmeasurable state. By singular value decomposition of system input matrix, a reduced order system is obtained for the design of sliding mode surface. A new adaptive sliding mode controller based on system output is presented to guarantee that the closed loop system is uniformly ultimately bounded. Four examples are provided to illustrate the effectiveness and applicability of the proposed control scheme.
