基于强跟踪滤波器的在线故障诊断方法

A Method of On-Line Fault Diagnosis Based on Strong Tracking Filter

为了能在线诊断非线性系统故障 ,介绍了一种基于参数估计为主的强跟踪滤波器方法。由于该方法可得到比较准确的非线性系统状态与参数估计 ,系统的状态与参数可以得到辨识 ,因此该方法是一种很有效的在线故障检测与诊断方式。

In order to diagnose the fault of a nonlinear system,a method of strong tracking filter based on parameter estimate is introduced.The method would be quite effective in the on line fault detection and diagnosis,bacause the state and parameters of the system can be rather accurately identified in the method.Simulation studies demonstrate that the method is really effective.
