摘　　要：分析了电动助力转向系统比例控制电动机电流的方法,发现系统有振动。在此基础上,提出了对电动机电流进行微分补偿的改进措施,设计了比例加微分控制电动机电流的方法。分析结果证实,所设计的比例加微分控制电动机电流具有良好的性能。试验结果表明,提出的控制方法是有效的,对电动助力转向开发有指导意义。The method of the proportion control of the motor current is analyzed. The oscillations of Electric Power Steering System are found. On the basis of it, the improvement measures of the electric current based on a differential compensation are proposed. The method of proportion-plus-derivative control is designed. The analysis result shows that the design of the proportion-plus-derivative control of the motor current has a good function. The test shows that the control method is valid, and has a guiding significance to development of electric power steering.
