摘　　要：研究了PID控制的助力特性。根据转矩信号和车速信号确定助力电动机的目标转矩,通过PID控制参数使得电动机施加在转向轴的助力转矩能快速跟随目标转矩,达到助力转向的目的。分析结果证实,所研究的PID控制策略具有良好的助力性能。试验结果表明:提出的控制策略是有效的。The power characteristic based on PID control strategy is studied.The target motor torque is determined by the torque signal and speed signal.The motor to exert a positive force in the steering shaft torque can quickly follow the target torque by tuning the PID control parameters to achieve the purpose of power steering.Analysis result shows that the PID control strategy is good for power performance.The test shows that the control strategy is valid,and is useful for the development of electric power steering.
