Title
Adaptive Fuzzy Output Feedback Control for Nonlinear Nonstrict-Feedback Time-Delay Systems with Full State Constraints
Abstract
This paper investigates the adaptive fuzzy output feedback control problem for a class of nonstrict-feedback time-delay systems subject to full state constraints. An observer is designed to estimate the unavailable systems states. By incorporating the barrier Lyapunov function and introducing a variable separation approach, an adaptive fuzzy output feedback tracking controller is systematically designed to ensure that the full state constraints are not violated and all the signals of the closed-loop systems are uniformly ultimately bounded. At the same time, the tracking errors can fluctuate around the origin within a small neighborhood by appropriate choice of the design parameters. Finally, two simulation studies are worked out to show the effectiveness of the proposed approach.
