摘要：This paper considers the event-based adaptive fuzzy fixed-time tracking control problem for nonstrict feedback nonlinear interconnected systems with actuator faults and funnel constraints. A fixed-time control framework with funnel error variables is constructed, which guarantees the fast convergence performance and the static performance of tracking errors. Meanwhile, an adaptive decoupling control strategy is designed to conquer the design difficulties caused by the full-state coupling of subsystems and the output variables coupling among subsystems. By combining the boundary estimation method and the event-triggered mechanism, the control laws are designed in the backstepping procedure, which can eliminate the effect of actuator faults and save communication costs for control signals. It is shown that all signals of the closed-loop systems are bounded and the tracking errors converge to the small neighborhoods of origin in a fixed time. Finally, the effectiveness of the proposed control scheme is verified by some simulation results.
