Abstract: This paper focuses on the online fault detection problem for networked control systems with unknown network-induced delays. In the study, a fault detection model was established for the impact of the unknown network-induced delay. Based on the model, the fault detection filter was constructed, and then the corresponding fault detection problem was converted to an optimisation problem. Finally, a numerical simulation shows that the proposed online fault detection algorithm is not only sensitive to the fault, but also robust to the unknown disturbance caused by the delays.
