摘要
以四个敏感器的冗余系统为例,对采用冗余敏感器的惯导系统的可靠性进行了分析,对四个敏感器构成的捷联惯导系统的可靠性进行了仿真实验,验证了冗余敏感器可以提高系统可靠性结论的正确性。文中给出非正交敏感器测量值向惯导系统正交坐标系转化的方法和转换矩阵。最后对冗余敏感器的配置方式进行了分析。通过仿真实验,得到敏感器最佳配置的条件。
The author analyzes the reliability of SINS and simulates SINS based on the SINS with four redundant inertial instruments. It is proved that the redundant inertial instruments can improve the reliability of SINS. The author presents a new method converting the measurements from the non-orthogonal frame to the orthogonal frame. Finally the result of the optimal configuration of redundant inertial instruments is proved.
