基于模型的混杂系统中控制器故障诊断方法

Model-based diagnosis of controller fault in hybrid system

为解决混杂系统中控制器故障诊断问题,提出一种混杂系统故障发生在控制器与设备组件之上的新诊断方法,解决了控制器故障检测与诊断问题,并给出解决上述问题的基本诊断算法。实验结果表明,该算法程序简单且效率较好,对于复杂的被诊断对象可以满足实时性。

In order to solve the fault diagnosis problem of controller in hybrid system, a new diagnostic method was proposed for faulty events that occur on monitors or components. Using this method, monitor faults in hybrid systems can be diagnosed. An elementary diagnostic algorithm was also proposed. The experiment results indicate that the algorithm is easy to produce into procedure with high efficiency. Real time diagnosis for complex objects can be realized.
