Adaptive control of stochastic switched nonlinear systems

In this paper, an adaptive fuzzy tracking control approach is proposed for stochastic switched nonlinear systems in lower triangular structure. Fuzzy logic systems are used to approximate the unknown nonlinearities and backstepping technique is employed to construct adaptive fuzzy controller. It is proved that the designed controller can guarantee that all the closed-loop signals are bounded and the system output converges to a small neighborhood of the desired reference signal.
