Abstract :
Electric power steering (EPS) systems have many advantages over traditional hydraulic power steering systems in engine efficiency, space efficiency, and environmental compatibility. A brief introduction of the structure and principle of EPS system is presented and the control scheme is proposed. Based on the principle of brushless DC (BLDC) motor, a novel method for modeling and simulation of BLDC control system is developed in Matlab/Simulink. Organically combining the blocks, a test was performed on a timing system with current hysteresis control. The plot of the motor assisted torque versus the armature current was demonstrated. The feasibility, high reliability of the system and the validity of the control method are proved by the results. And a new kind of test bench model is offered for designing and verifying EPS system.
