| 英文摘要 |
| The paper studies model observer based robust fault detection system for an aircraft hydraulic servo system, presents the disturbance compensation and adaptive threshold design methods, and enhances the robustness and sensitivity using them. Simulations demonstrate that the detection method proposed can robustly and rapidly detect the small abrupt and slow drift faults of the servo system. |
