Abstract :
On-line fault detection problem for a type of SISO networked control systems was studied. The delay of forward loop can be avoided by located the smart nodes. A self-adaptive predicted technology was used to compensate the delay of feedback loop. The networked induced delay can be obtained by time-stamp. A fault detection algorithm for a type of fault was presented to monitor the NCS on-line. The feasibility is tested by theory and digit simulation. Finally, the validity was tested by both off-line and on-line real-time simulation.
