Study On Sensor Robust Fault Detection Of Control System

The paper first summarizes the phylogeny of the sensor fault diagnosis, and then introduces the academic achievements during recent years.After thoroughly researching on the methods of the robust fault detection based on the observer ,three robust fault detection design methods are put forward .Resort to Matlab ,these methods are applied to design the sensor fault diagnosis of the superheated steam system and two four-order linear dynamic systems ,and the simulation results demonstrate the effectiveness in distinguishing the typical sensor faults against the disturbance .At last ,this paper points out the problems to be solved and possible research directions.Li Feng(Control Theory and Control Engineering)Directed by Prof. SUN Wanyun...
