摘要
电磁式助力转向是汽车动力转向系统领域的一项新结构。电磁助力器工作电流的控制是电磁式助力控制系统软件设计的一个最基本的控制策略和方法。文中详细地介绍了电磁助力器工作电流模糊控制器的设计方法。文中也给出了方向盘把持力在阶跃输入下的时域响应的仿真结果,该结果表明电磁助力系统具有较好的响应特性。
Electromagnetic power steering(EMPS) is a new automotive power s teering system. The current control of electromagnetic power equipment is a basi c control strategy for the software design of EMPS. In this paper, a way of the design for fuzzy controller of EMPS is discussed emphatically. Finally the simu lation about the time response of force on steering wheel under step input was f inished. It is shown that the control effect is better.
