摘要
为了研究车辆动态负载高度时变性和随机性对电动汽车用开关磁阻电机驱动系统影响特性并实现电机驱动系统性能评价分析,基于车辆行驶工况动态负载特性,在开关磁阻电机非线性数学模型及车辆动力学模型基础上,分别建立了电动汽车用开关磁阻电机驱动系统及电动汽车动态载荷仿真模型.并根据电动汽车行驶过程中2个典型工况对建立模型进行了实时仿真,得到了开关磁阻电机主要性能参数随车辆动态载荷变化的响应曲线.分析并评价了开关磁阻电机驱动系统在各工况下的动态驱动特性,仿真结果对电动汽车车型设计及改进具有很好的参考价值.
In order to analyze the effect of the vehicle time variant and random load on the switched reluctance motor（SRM） drive and evaluate the drive system performance,the nonlinear dynamic SRM drive and vehicle dynamic load simulation models are established in the Matlab / Simulink environment based on the SRM and vehicle mathematical model w ith actual loads in vehicle.And the dynamic simulation of the developing electric vehicle is carried out based on tw o typical movements of the vehicle.The drive performance of the SRM drive is analyzed by the SRM drive response including the motor current and the output torque w hich are affected by the vehicle dynamic load.The simulation results are significant for the design and improvement of the electric vehicle.
