We are particularly interested to diagnosis faults af- fecting the Exhaust Gas Recirculation (EGR) and the variable Nozzle Turbine (VNT) actuator valves. To accomplish this goal, a residual generator based on a nonlinear mean value model of the diesel engine is proposed using a bank of observer. Each residual on the proposed scheme is based on a nonlinear unknown input observer and designed to be insensitive to only one fault. By using this kind of scheme, the actuator faults can be easily isolated since only one residual goes to zero while the others do not. A decision al- gorithm based on multi-CUSUM is used. The perfor- mances of the proposed approach are shown through the application to a diesel engine model.Show less >
