Event-Triggered Adaptive Fuzzy Tracking Control for Nonlinear Systems With Unknown Control Directions
针对未知控制方向的非线性系统，设计了一种事件触发自适应模糊跟踪控制器，在保证跟踪误差收敛到任意小邻域的同时，降低了控制器到执行器的通信负担，并排除了Zeno行为。
This article addresses an event-triggered adaptive fuzzy tracking control problem for nonlinear systems with unknown control directions. To achieve the practical tracking, fuzzy logic systems are employed to approximate unknown nonlinear function. Nussbaum functions are adopted to address the problem of the unknown control directions. The newly designed controller not only guarantees the tracking error that converges to an arbitrary small neighborhood near the zero but also reduces the communication burden from the controller to the actuator. Moreover, the feasibility of the proposed event-triggered mechanism is verified by excluding Zeno behavior. Finally, the simulation result proves the effectiveness of the designed control scheme.
