Sensor Fault Detection Method Based on Set Membership Filter and Ellipsoid Calculation
In order to solve the problem of unknown fault signal diagnosis,a set membership filter sensor fault detection method based on ellipsoid calculation is proposed.In order to prevent data collision and reduce energy consumption,the weighted one-time discard scheduling is used to control the information distribution between the sensor unit and the filter.Then,the distributed set membership filtering method is effectively applied to deal with the unknown but bounded fault detection problem under wtod protocol.Furthermore,by dealing with the optimization problem with certain inequality constraints,two ellipsoids in the sense of minimum trace are optimized.Finally,the simulation results show that the proposed method can effectively detect the unknown fault signal of sensor networks,and it does not need to know all the States,which greatly expands the scope of application.
