| Abstract: | The structure and the principle of the EPS（Electric Power Steering） system is introduced in this paper.The EPS was modeling and simulated in the Matlab/Simulink after the analysis of the mathematical model.PID-Fuzzy control strategy was adopted for the closed-loop tracking control of the objective current in the motor.Simulation results show that： with the EPS system based on PID-Fuzzy control,the vehicle has a better performance of power steering features,and it proves the effectiveness of the control strategy. |
