Fault Diagnosis Theory and Its Application in the Electromechanical System
Qian Guang-di · Experiment Science and Technology · 2009
This paper introduces naissance and task of fault diagnosis theory;And in a nutshell it illuminates fault diagnosis method based on resolution model,fault diagnosis method based on knowledge and fault diagnosis method based on data drive;And in great detail it introduces the process of fault diagnosis method based on observer,then illustrates how to apply fault diagnosis method based on observer in the electromechanical system,and gives out the simulation result of Matlab. Finally the paper,by analyzing the simulation result,concludes that fault diagnosis method based on observer can monitor system better,but orientating definition of fault is insufficient to complex system.
