摘要：

In this paper, a robust diagnosis in closed loop dynamic system based on bond graph (BG) approach is proposed. The methodology uses the linear fractional transformation (LFT) form to eliminate the parameter uncertainties in the residual. The proposed method develops a threshold against measurement noises with the sensitivity of the residual to faults. Finally, simulation results are presented to show the performance of the proposed approach.
