摘要
针对一类具有范数有界不确定性的线性连续随机系统,研究了极点指标、H_∞指标和方差指标约束下的动态输出反馈满意容错控制问题。在执行器连续增益故障模型下,分析了容错控制中3类期望指标的相容性,并给出了3类指标约束下具有最小能量的动态输出反馈满意容错控制器的设计方法。仿真算例验证了方法的有效性和对系统进行满意容错控制的必要性。
A dynamic output feedback fault-tolerant control system was developed based on circular pole index, steady variance index and H-infinity index constraints for linear continuous stochastic systems in the presence of parametric uncertainties.The consistency of these performance indices is analyzed for fault-tolerant control of actuator continuous gain faults.A minimum control-cost fault-tolerant controller is designed as a convex optimal problem with these constraint indices.A simulation shows the validity of...
