Overview

abstract

• The conditions for fault detection and isolation (FDI) based on differential geometry are analyzed for both linear and nonlinear DC motor configurations. Hence, the sets of faults that can be detected and isolated are deduced, and it is derived that the presence of an unknown perturbation in the mechanical equation of the motor limits the capability of detecting mechanical faults. Based on the geometric approach, observers are developed to generate fault residuals. Simulation and experimental results are shown to verify the analysis. © 2007 World Scientific Publishing Co. Pte.
