摘要 针对含有不确定参数的离散时滞系统,在执行器增益故障情况下,研究了含时滞记忆的状态反馈满意容错控制器的设计问题.在采用合理的执行器故障描述条件下,分别给出了无外界扰动输入时含有时滞记忆和无时滞记忆状态反馈鲁棒容错控制器的存在条件;进一步给出了在H∞扰动衰减指标约束下,含有时滞记忆和无时滞记忆状态反馈鲁棒容错控制器的设计方法.仿真算例验证了该方法的有效性. The problem of state feedback satisfactory fault-tolerant control is investigated for uncertain discrete-time delayed systems against actuator failures. Sufficient conditions for the existence of robust fault tolerant stabilization controllers with time-dalay memory are given. Then, the satisfactory fault tolerant controllers with H∞ constraints are designed based on the solutions of a group of linear matrix inequalities. Numerical examples show the effectiveness of the results.
