基于卡尔曼滤波器的控制系统传感器故障诊断

Fault-Diagnosis of Sensors Control System Based on Kalman Filter

控制系统故障诊断在生产中十分重要,而传感器作为控制系统中最容易发生故障的环节,对其故障做出及时正确的预报尤为重要。介绍了卡尔曼滤波器的原理,以及基于卡尔曼滤波器的控制系统传感器故障诊断方法,从仿真结果可以看出这种方法在故障诊断中的实用性和有效性。

The control system failure diagnosis is crucial in power generation. As the sensor is a part most prone to fail, timely, accurately forecasting of its failures is particularly important. This article describes the principle of the Kalman fiher,and the sensor fault diagnosis method of the control system based on the Kahnan filter sensor. The simulation results show that this approach to fault diagnosis is both efficient and practical.
