| 摘 要： | 针对电动汽车专用PMSM控制系统的动态损耗问题,提出了一种改进的效率优化策略。分析了PMSM损耗模型,推导出系统损耗和定子磁链的关系,得到最优磁链与定子电阻相关。基于小波神经网络的动态定子电阻补偿方法,进而解决了由于最优磁链受动态定子电阻影响使得最优磁链难以准确计算的问题,以使电机驱动系统效率最佳。利用Matlab/Simulink仿真软件建立了系统模型,仿真结果证明,该策略能有效提高电动汽车驱动系统的效率。

| Abstract: | An improved strategy was proposed for the efficiency optimization of EV-motor control system.Based on the power loss model of PMSM,the relationship between system loss power and stator flux linkage is deducted and the optimal flux is related to stator resistance.A stator resistance compensation scheme is presented based on wavelet neural network to address the difficulty in accurately calculating the optimal flux with dynamic stator resistance present.The validity of the proposed strategy is proved by the simulation of the system model using matlab/simulink. |
