摘要：

In this paper. ",e present a method for the fault detection based oil the residual acneration. The inain idea is to reconstruct the outputs ofthe system from the measurements using the extended Kalman filter The estimations are cornpaied to the values of the reference model and so, deviations are interpreted as possible faults The reference model is simulated by the dynarnic hybrid simulator. PrODHYS The use of this illethod is illustrated thrOUgh an application in the field of' chemical processes C 2009 Curtin University of Technology and John Wiley & Soils, Ltd.
