摘要
设计了一种鲁棒自适应观测器,通过其输出残差对传感器故障信息敏感性很高,而对系统故障信息敏感性很低的特点,实现了故障区分。设计了一套故障区分控制系统和检测策略,用以区分两类故障,以免发生误判现象。举例说明了该策略的可行性和有效性。
A robust adaptive observer is presented in this paper. The observer is sensitive to the sensor fault but robust to the system fault, so the fault identification is achieved . Then a method of fault identification and control system is advanced to identify the two kinds of fault to avoid judging falsely. The effectiveness of the method is shown by simulation results.
