Abstract :
This paper investigates development of a nonlinear Fault Detection and Isolation (FDI) strategy for redundant reaction wheels in the attitude control subsystem (ACS) of a satellite. Due to the coupling effects and dependencies in reaction wheels, the necessary condition for applying a standard geometric FDI approach is not satisfied. To remedy this problem, a set of detection filters are designed whereby through a combination of the residuals the FDI decision making is accomplished successfully. The simulation results presented demonstrate the effectiveness of our proposed FDI method.
