Objectives: A novel approach for diagnosis and control design that compensates sensor fault effects in electric power steering system (EPS) is proposed. Methods/Statistical Analysis: A Luenberger observer is used to estimate the fault of torque sensor for the EPS system. The fault tolerant control (FTC) based an inverse model of bond graph (BG) is used to compensate the fault of torsion bar sensor signal. The proposed control strategy presents an opportunity to improve EPS system performance and also reduce system complexity. Findings: The findings achieved are simulation tests, showed that the application of the synthesized law on the experimental of the EPS system show the effectiveness of the proposed approach. Application: The fault tolerant control based a bond graph model is an important step allows an improvement the rapidity of the compensation of fault in the system.
