An Algorithm of Fault-Tolerant Control with State Feedback Control System
-
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散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.Abstract: 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 fault-tolerant 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.
