摘要
本文提出了在状态反馈控制系统中,当某个传感器失效时,由其余完好的状态反馈回路平均分担已失效回路的控制作用的容错控制思想.由此所设计的线性状态反馈容错控制系统在任一传感器失效的情况下,均具有从正常系统的控制到故障系统的控制的无扰动切换功能和良好的静动态性能.该法简单、实用,具有广泛的工程应用价值.
In this paper, a new algorithm of fault-tolerant control is presented. When one of the sensors is failed in a state feedback control system, the remaining state feedback circuits will bear the control action of the fault circuit averagely. This linear state feedback fault-tolerant control system has the function of no disturbed transposition from normal control to faulttolerant control, and has good performances whenever any sensor is in fault. The method is simple and practical, and has very useful value of engineering application.
