Abstract :
This paper presents a method for fault detection and residuals evaluation, applied on electromechanical test bench system in the presence of backlash phenomenon and parameter uncertainties. The analytical redundancy relations (ARRs) are generated using uncertain bond graph model, in linear fractional transformation form (LFT). Through the presented method, one can distinguish between backlash default and system parameter variation. Simulation tests presented in this paper show the influence of dead zone magnitude and system parameters variations on residuals evaluation
