| Abstract: | Abstract: This paper discusses fault diagnosis for network control system with random delays. Two general fault detection filters are designed: Kalman filter and H1 filter. The former is obtained using an iteration method, and the latter is realized with linear matrix inequalities (LMI) and augmented matrices to ensure the smallest possible error between the residual and the fault. A numerical example is provided to showeffectiveness of the present methods. |
