Application of a Nonlinear Fault Detection and Isolation Scheme to an Aerocraft’s Nonlinear Closed-Loop System

J. Zhou and X. Huang

Abstract:
In this study, the nonlinear fault detection and isolation (FDI) scheme is successfully applied to the aerocraft’s nonlinear closed-loop control system, which is established by using the dynamic inversion theory. The nonlinear FDI scheme consists of a bank of nonlinear adaptive estimators. One of them is the fault detection and approximation estimator, whereas the others are used for fault isolation (each associated with a specific type of fault). A type of fault that has occurred can be isolated if the residual associated with the matched isolation estimator remains below its corresponding adaptive threshold and at least one of the components of the residuals associated with all the other estimators exceeds its threshold at some finite time. The simulation results show the effectiveness of the application.
