Adaptive fuzzy tracking control for a class of nonaffine stochastic nonlinear systems

This paper considers the problem of the adaptive fuzzy tracking control for a class of nonaffine stochastic nonlinear system without lower triangular form. Based on fuzzy logic systems´ universal approximation property, an adaptive fuzzy controller is proposed, which guarantees that all the signals in the closed-loop system are bounded in the sense of mean quartic value and the output tracking error eventually converges to a small neighborhood around the origin. Simulation results are provided to illustrate the effectiveness of the proposed scheme.
