摘要：
This paper is devoted to the issues of robust fault detection for a class of observer-based feedback control systems with model uncertainties, disturbances and faults. As the observer-based feedback controller structure allows a direct access to the residual signal, a robust post-filter is designed such that the modified residual satisfies the optimized robustness against disturbances under a desired sensitivity to faults. Moreover, the detection performance of the designed fault detection system is analyzed. Simulation results are given at the end of the paper to demonstrate the effectiveness of the proposed schemes.
