A Return-to-central Control Strategy for Electric Power Steering System by Controlling the Angular Velocity of Steering Wheel

  • 摘要: 针对已有电动助力转向(EPS)系统高速回正超调,低速回正不足的问题,提出了基于控制方向盘转速的回正控制策略。建立了齿条式电动助力转向系统动力学模型;阐述了回正特性曲线的获取方法;通过Adams/Simulink对控制策略进行了仿真试验。在控制策略方面跳出了以往的基于方向盘转角的模糊PID控制的局限,仿真分析表明基于方向盘转速控制的回正控制策略实现了理想的回正效果,较已有的回正控制不存在回正不足或超调现象,且回正过程无方向盘震荡现象,达到了迅速、准确的回正效果。
