Actuator fault detection for a diesel engine using observer method based

This paper proposes a framework for Fault Detection FD in linear systems developed in the context of systems invertibility. It deals with issues of actuator fault, so a diesel engine is introduced as a benchmark for model-based fault detection. The purpose is to provide a simple, industrial system as a platform for a new formulation of linear system diagnosis problem. FD performance specifications are provided. They include conditions for detection probability. Using the diesel engine model presented by two subsystems: the process subsystem and the actuator subsystem, simulations and experimental results show the advantages of the FD scheme observer based.
