摘要
针对一类可能出现传感器故障的不确定系统,分别采用状态反馈控制和静态输出反馈控制,提出了基于LMI条件的鲁棒D稳定化容错控制方法。该方法不仅使得系统在传感器发生故障时仍具有完整性,而且还使得闭环系统对于允许的参数不确定性在指定的圆盘区域内具有鲁棒稳定性。数值算例和仿真结果表明该方法简单有效。
Based on LMI conditions of disk stability, a method of robust fault-tolerant control against sensor faults for uncertain systems is presented via memoryless state feedback control and static output feedback control respectively. By using this method, the closed-loop system not only keeps integrity but also is robust stable in given disk area for all admission parameter uncertainties when sensor faults occur. Numerical example and simulation results demonstrate that the method is simple and effective.
