摘要
作为电动汽车的核心组件之一,驱动控制系统决定汽车性能的好坏。文章以电动汽车驱动控制系统为研究对象,分析了电动汽车驱动控制系统的基本组成,构建了驱动控制系统的数学模型,指出了定子绕组电感测定法测量转子位置的缺点,选用矢量控制作为转子位置检测的改进工具,着重分析了无速度传感器控制下电动汽车驱动控制系统。仿真结果表明该系统在电动汽车驱动控制中具有较好的可行性。
As one of the core components of electric vehicles,the drive control system determines the performance of the vehicle.By taking the drive control system of the electric vehicle as the research object,this paper analyzes the basic composition of the drive control system of the electric vehicle,constructs the mathematical model of the drive control system,and points out the shortcomings of measuring the rotor position by measuring the inductance of stator winding,and selects the vector control as an improved tool for the rotor position detection.The drive control system of electric vehicle without speed sensor control is presented.The simulation results show that the system is feasible in the drive control of electric vehicles.
