摘要
针对线性定常系统,采用连续增益故障模型,提出了考虑执行器故障的可靠 H_∞控制问题.通过对具有执行器故障线性定常系统的分析,利用 LMI 分别给出了次优可靠 H_∞控制器和最优可靠 H_∞控制器存在的充分条件.通过比较,进一步看出对系统进行最优可靠 H_∞控制器设计的必要性.
Aiming at linear time - invariant system, by continuous gain fault model, puts forward the reliable H∞ control problem considering actuator fault. By analysing the linear time - invariant system with actuator fault, gives the sufficient condition of hypo - optimal and optimal reliable H∞ controller by LMI. By comparison, finds that it is necessary to design optimal reliable H∞ controller.
