不确定广义系统鲁棒容错控制

Robust fault-tolerant control for uncertain singular systems

针对一类不确定性广义系统,运用线性矩阵不等式方法,给出了一种鲁棒容错控制器设计方法。利用该方法设计的闭环系统,对执行器发生故障具有完整性,而且对所有的容许的参数不确定性具有鲁棒性。最后用一个数值例子验证了该设计方法的有效性。

A design method of robust fault-tolerant feedback controller is put forward for uncertain singular systems by linear matrix inequalities. It is shown that the proposed state feedback systems are of integrity and robustness in the presence of all admissible parameter perturbations against actuator failures. The controller can be obtained by solving LMI, which is tractable. Finally, a numerical example is given to illustrate the effectiveness of the proposed approach.
