Fault Detection of Networked Control Systems Based on Kalman Filter

The fault detection for networked control systems with network induced time delay is discussed in this paper. The Kalman filter is designed to compensate the time delay. The residue is only related to fault and random disturbance. By computing the residue between the output of the practical system and the output of the Kalman filter, the fault detection scheme of NCS is given. The simulation results illustrate effectiveness of the proposed delay compensation method and fault detection method.
