title: Fuzzy Adaptive Tracking Control of Constrained Nonlinear Switched Stochastic Pure-Feedback Systems.
abstract: In this paper, the fuzzy adaptive control problem for a class of switched stochastic nonlinear systems in pure feedback form with output constraint is addressed. By proposing a nonlinear mapping, the constrained system is transformed into an unconstrained one, with equivalent control objective. All signals in the closed-loop system are proved to be semiglobally uniformly ultimately bounded. Meanwhile, the output constraint is satisfied and the output tracking error converges to an arbitrarily small neighborhood of zero. Finally, the applicability of the proposed controller is verified by a simulation example.
