Abstract：In this paper , it is aimed at the possible disturbance and the noise problems caused by the road random excitation and the torque sensor measurement in the electric power steering system to construct the vehicle dynamic model that consists of the EPS system in the application of the CarSim/Simulink co-simulation software, design the EPS control strategy based on the LQG/LTR and analyze the system stability. The result shows that the EPS system controlled by the LQG/LTR can provide the driver with the steering portability and satisfactory steering feel, improve the system stability and restrain the interfering noise in the system effectively.
