| Abstract: | In this paper, the configuration, operating principle of platform-strapdown master and slave redundancy attitude control systems and modes of fault diagnosis, alteration and reconsititute are introduced. A semi-physical simulation test is taken by inducting typical fatal fault mode to the system at several special time points from different channel respectively so as to observe and recorder the adaptability and response characteristic of attitude control system, and the effects of fault diagnosis threshold value on system as well. The semi-physical simulation test proved that the redundant program is correct and available. |
