Research on the robustness of the filter against noise by actuator failure research. Firstly, the design of detection filter under multi-fault condition is studied by using the method of feature structure configuration. The basic structure of the gain matrix is given. Then, the design of the optimal fault detection filter for process noise and measurement noise is studied. An algorithm of gain matrix, finally using a certain type of aircraft equations for simulation. Simulation results show that the optimal fault detection filter can effectively suppress the impact of noise on the system
