| 中文摘要:对于一类广义时变不确定系统，在执行器故障情况下给出了系统具有容许性的充分条件，并设计反馈控制器使其满足给定的 H∞ 干扰衰减指标，使得系统在正常与故障情况下都具有容许性.最后给出数值算例来证明结论的有效性. |

| Robust H-infinity Fault-tolerant Control Against Actuator Failures for Descriptor Time-varying System |
|
|
| Abstract:A class of descriptor time-varying uncertainty system has been investigated.In the case of actuator failures，a sufficient condition of the system’s stability is given，and a state feedback controller is designed to satisfy the pre-set H-infinity disturbance attenuation index so as to keep certain H-infinity norm performance in the normal condition as well as in the event of actuator failures.A numerical example shows the effectiveness of the proposed method. |
