Fuzzy Approximation of a Novel Nonlinear Adaptive Switching Controller Design

In this paper, an indirect adaptive fuzzy switching control scheme with average dwell-time method is proposed for switched strict-feedback nonlinear systems. By employing fuzzy logic systems to approximate unknown nonlinear functions and combing with the indirect adaptive fuzzy switching controller design procedure, the proposed control scheme can guarantee that all the closed-loop signals are boundedness, and the output of the systems converges to a small neighborhood of the desired trajectory. Finally, simulation results have been conducted to demonstrate the effectiveness of the proposed controllers. It has also been shown that the convergence of parameters and output tracking errors are smoother and faster with the proposed scheme, compared with the conventional adaptive fuzzy control methods.
