| Abstract: | Networked control system (NCS) was regarded as a sampled-data control system with output time-delay and a mathematical model was set up. So a fault observer was constructed, and the indicator of system faults-residual was generated. Then fault detection and isolation (FDI) approach based on this observer was introduced. The design algorithm of the FDI observer was summarized. At last, an example is given to show the approach is feasible. |
