摘要 针对非线性系统的容错控制问题,以广义双线性系统为研究对象,基于非线性系统H∞控制的概念,提出了利用状态反馈控制器实现广义双线性系统容错控制的方法,给出了状态反馈控制器的存在条件和设计过程。设计的状态反馈控制器在无执行器故障和存在执行器故障的情况下,都能保证闭环系统渐近稳定,且闭环输入输出信号满足H∞性能指标,从而实现系统的容错控制。最后的仿真结果证明了该方法的有效性。 To study the problem of fault-tolerant control for singular bilinear systems, the concept of H∞ control for nonlinear systems is used to and develope state-feedback controllers. The existence conditions and design methods of the state-feedback controllers are proposed. The controllers, whether the actuators are normal or abnormal, could ensure exponential stability of the closed-loop system and the required H∞ norm performance index. And then the fault-tolerant control is achieved. Finally, a simulated example is given.
