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.
For the discrete-time systems with uncertain parameters, the design of state-tolerant controller with time-delay fault-tolerant controller is studied under the condition of actuator gain failure. Under the condition of reasonable actuator fault description, The existence conditions of the robust fault-tolerant controller with time-delay memory and non-time-delay memory state feedback are presented for the disturbance input without external disturbances. Furthermore, under the constraint of the H∞ disturbance decay index, the state feedback with delay memory and no memory state feedback The design method of robust fault-tolerant controller is shown in the simulation examples to verify the effectiveness of this method.
