On the design of robust adaptive fuzzy sliding mode controller for nonlinear uncertain systems with hysteresis input

摘要

The main objective of this paper lies in providing a control strategy for a class of nonlinear hysteretic systems in presence of external disturbances and system uncertainties. Fuzzy logic systems are utilized to approximate the unknown nonlinear behaviors and sliding mode technique is used to construct an adaptive controller. The proposed control scheme ensures that all signals in the closed-loop system are bounded, and the tracking error eventually converges to a small neighborhood of the origin. Simulation results are provided to illustrate the efficiency of the suggested approach.
