Study of sensor fault detection based on modified SVM algorithm

Sensor is an essential device in automation control system, and the reliable sensor signal has the massive benefits of the normal operation of whole system. This paper proposed an improved support vector machine (SVM) which is modified by clone select algorithm (CSA) for sensor fault detection. CSA - SVM observer is established by monitoring sensor in real-time, so as to find sensor fault in time. Simulation results show that the algorithm can be effective for fault detection.
