| 摘 要： | 研究了圆形区域极点约束下Delta算子描述的不确定线性系统的鲁棒容错镇定问题.基于Riccati方程,导出了当Delta算子系统存在不确定性和执行器故障时,将闭环系统极点配置到指定圆盘内,确保系统鲁棒容错镇定的充分条件;运用线性矩阵不等式(Linear Matrcx Inequality,LMI)方法,对Delta算子不确定系统进行状态反馈设计,给出了系统在区域极点约束下鲁棒容错控制器存在的充分条件,并通过求解LMI得到鲁棒容错控制器的设计.通过数值仿真验证了该方法的有效性.

| Abstract: | The robust fault-tolerant stabilization problem of circular regional pole assignment for delta operator formulated uncertain linear systems is studied in this paper.A sufficient condition of robust fault-tolerant stabilization is derived using Riccati equations for the delta operator systems with uncertainty and actuator failure when allocating the closed-loop poles into a specified circular disk.In terms of a linear matrix inequality(LMI) approach,a sufficient condition for the existence of a robust fault-... |
