摘　　要：以电动车转向机构中的电机存在死区为切入点,提出一种死区逆变换补偿电机控制方法。通过对执行机构实验数据的分析推导出其数学模型,并且针对机构存在死区的特点,设计了逆变换补偿的控制算法,以消除死区对控制系统的不良影响。利用MATLAB仿真工具,获得了系统控制所需的参数,然后把算法以及参数移植到实车ECU进行验证。理论分析和实车实验证明,该控制方法行之有效。A control method based on dead-zone inverse transforming compensation was presented for electric power steering system on a EV whose execution mechanisms include dead-zone. The mathematical model for execution mechanisms from empirical data was derived and a control approach called ＂dead-zone inverse transforming compensation＂ was designed to eliminate ill effects caused by dead-zone. The control parameters were got by MATLAB and the algorithm and parameters were tested on a real EV. It was proved that the method was effective.
