Fuzzy sliding mode controller design for uncertain time-delayed systems with nonlinear input
In this paper, the theory of sliding mode control is employed to develop a fuzzy controller for uncertain dynamic time-delayed systems with series nonlinearities. The control method provides a simple way to achieve asymptotic stability of the uncertain time-delayed system. Other attractive features of the method include a minimal realization of the fuzzy controller in spite of the number of state variables, as well as insensitivity to the uncertainties and disturbances, In addition, the method is capable of handling the chattering problem inherent to the sliding mode control easily and effectively. Also, this fuzzy sliding mode controller can be extended to handle the MIMO system. Simulation results are presented to demonstrate the power of the method. (C) 2002 Elsevier B.V.
