| 摘要: |
| 针对基于模型的机电控制系统BIT中的虚警问题，分析了系统中的信息不确定性和产生虚警的机理，基于最优未知输入观测器方法设计了BIT故障检测诊断系统，该系统对信息不确定性具有较强的鲁棒性，能够充分地抑制虚警。在某机电跟踪与稳定伺服平台BIT系统上进行了试验研究，结果表明机理分析正确，所提方法有效。 |

| Abstract: |
| The false alarm of the BIT based on model in the mechatronics control system is studied. Firstly, the information uncertainty of the BIT system and the reason of BIT false alarm are analyzed. Then, the BIT system is designed by the application of the optimal UIO(unknown input observer). It is robust to the information uncertainty, and can decrease the false alarm. Finally, the experimentation on the BIT system of stabilization and automatic pointing and tracking platform is made. The result shows that the analysis is correct and the method is effective. |
