Time-stamped fault detection for SISO NCS: A self-adaptive predicting algorithm

Fault detection problem for a type of SISO networked control systems is studied. We can avoid considering the delay of forward loop by located the smart nodes. The networked induced delay can be obtained by time-stamp, and coupled with identification technology, a self-adaptive predicted technology is used to compensate the delay of feedback loop. A fault detection algorithm for a type of fault is presented to monitor the NCS on-line. The feasibility is tested by theory and digit simulation.
