| 摘 要： | 为了实现故障检测，在传统的Luenberger观测器的基础上，提出了一种Luenberger鲁棒故障检测观测器的设计方法及-H应的故障检测算法，并给出了在干扰存在的情况下，实现鲁棒故障检测观测器设计的充分必要条件．利用此观测器可以实现系统中带有确定性过程噪声的故障检测，且该鲁棒故障诊断观测器主要针对执行器故障的检测．仿真结果表明，该观测器可以克服噪声影响，实现鲁棒故障检测．

| Abstract: | In order to realize the fault detection, the design method of a robust observer for fault system detection based on the traditional Luenberger observer was proposed. The necessary and sufficient condition for the design of robust Luenberger observer was also given. The observer aimed at the detection of actuator fault. Fault detection can be realized by this observer for the system with certain process noise. The simulation result shows that the observer can come over the effect of noise and realize the robust fault detection. |
