摘要
针对冗余配置的惯导系统渐变型故障,提出了奇偶方程残差品质的概念及其模糊评估方法。并应用残差品质构成最小二乘加权阵,设计了冗余配置的惯导系统智能自适应渐变型故障容错方法。仿真结果表明,该方法对最多有两个捷联陀螺发生的渐变型故障能起到较好的检测和容错效果。
The concepts of parity equation residual quality as well as its fuzzy evaluation were presented to deal with the gradual fault in redundant SINS, and the residual quality was used to built the weighting matrix of least square, the intelligent adaptive fault tolerance for gradual fault was designed for redundant inertial instruments . Finally, the simulation results show that the method can detect and isolate no more than two soft faulty inertial components correctly.
