摘要
提出了一种基于统计数学的传感器故障诊断方法。该方法利用能量守恒方程的残差特征建立线性方程组 ,通过求解方程来完成多个具有固定偏差的传感器故障的检测和诊断。仿真试验表明该方法是可行的。
Provides a sensor fault detection and diagnosis method based on statistical mathematics. This method can detect and diagnose sensor fault with fixed deviation by establishing linear equations utilizing the residual characteristics of energy conservation equation and solving them. Simulation result shows the feasibility of the method.
