本文研究了一类具有执行器故障的不确定非线性系统的事件触发控制问题。允许执行器故障是未知的,故障总数可以是无限的。为了减少控制器与执行器之间的通信负担,设计了一种新的事件触发控制律。通过李雅普诺夫分析证明了所提出的控制协议确保闭环系统的所有信号是全局有界的,并且系统输出跟踪误差可以指数收敛到一个可以任意小的残差。
In this paper, we study the problem of event-triggered control for a class of uncertain nonlinear systems subject to actuator failures. The actuator failures are allowed to be unknown and the total number of failures could be infinite. To reduce the communication burden from the controller to the actuator, a novel event-triggered control law is designed. It is proved through Lyapunov analyses that the proposed control protocol ensures that all the signals of the closed-loop system are globally bounded and the system output tracking error can exponentially converge to a residual which can be made arbitrarily small.
