Modified Fault Isolation Filter for Networked Control Systemwith Send-on-delta Sampling
In this paper, the sensor data is transmitted only when the absolute value of difference between the current sensor value and the previously transmitted one is greater than the given threshold value. Based on this send-on-delta scheme which is one of the event-triggered sampling strategies, a modi.ed fault isolation.lter for a discrete-time networked control system with multiple faults is then implemented by a particular form of the Kalman.lter. The proposed fault isolation.lter improves the resource utilization with graceful fault estimation performance degradation. An illustrative example is given to show the ef.ciency of the proposed method.
