摘要
决策逻辑的阈值的确定是传感器故障诊断中的难点。将参数容差处理为随机变量,得到了随系统输入变化的阈值,理论和数字仿真结果都证明了该方法的正确性。
It is difficult to determine the threshold of the decision logic in the instrument fault diagnosis. By considering the allowances of component parameter as random variables and using Taylor expansion, the authors got the threshold varying with the input. Theory and digital simulation results show the correctness of this method.
