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。
A fault diagnosis method based on statistics is proposed. The method uses the residual characteristic of the energy conservation equation to establish a linear system of equations and solves the equations to complete the detection and diagnosis of multiple sensor faults with fixed deviations. Simulation results show that this method is feasible.
