| 英文摘要 |
| The problems related to the design of observer-based robust fault detection filter (RFDF) for uncertain linear systems with both modellling errors and unknown inputs were studied. By introducing a new performance index, the RFDF design problem could be formulated as an H-infinity-optimization problem, which was solved by suitably selecting RH-infinity post-filter and observer gain matrix such that the generated residual could achieve the best trade-off between the sensitivity to fault and the robustness to unknown input, modeling errors as well as control input. The design example and its simulation results demonstrate the effectiveness of the proposed approach. |
