In this paper, a model-based Fault Detection, Identification and Estimation (FDIE) scheme has been developed for the condition monitoring of the electro-hydraulic actuator (EHA) system. The scheme combines the use of a model of the EHA system with the multiple-model (MM) estimation algorithm to evaluate if fault is present, its cause and its severity. Using a multivariate nonlinear stochastic model, the EHA system dynamic responses are simulated in the presence of different types of faults. The… CONTINUE READING
