Return-to-center Control of Electric Power Steering

摘要：

The inertia,damp and friction force of machine reduces steering-wheel returnability,which drivers occasionally perceive as unpleasant. This phenomenon occurs in any EPS system regardless of motor type or mounting location. In this paper the fuzzy logic control scheme based on angle absolute position for steer wheel return-to-center is proposed to improve the return ability of electric power steering system. The different resistive force is imposed on the steer column through the reducer. The results of experiment bench show that the control strategy with angle absolute position feedback can improve the steer wheel return ability at any condition. It can overcome the disadvantage of algorithm uncertain. It is convenient for large volume production and serialization.
