摘　　要：降低内置式永磁同步电机的损耗,提高系统的效率,对于提高电动汽车的一次充电续驶里程具有重要意义。分析内置式永磁同步电机矢量控制系统原理,对三种不同的效率优化控制策略进行了系统建模仿真及实验,推导了一种基于内置式永磁同步电机的损耗最小控制算法,将铁损耗和交轴电感的变化考虑在总的电气损耗内的情况下,对该算法进行验证,实验结果表明,该最小控制策略效率更高,在新能源电动汽车的应用上具有广阔的发展前景。It has great significance for improving the one-charge driving mileage of electric vehicles by reducing the loss of internal permanent magnet synchronous motor and improving the efficiency of the system.The principle of the built-in permanent magnet synchronous motor vector control system is analyzed.The system modeling,simulation and experiment of three different efficiency optimization control strategies are carried out.A minimum loss control algorithm based on the built-in permanent magnet synchronous motor(PMSM)is derived.The algorithm is verified by taking the change of iron loss and axis inductor into consideration in the case of total electrical loss.The experimental results show that the efficiency of the minimum control strategy is highly effective,and it has a broad prospect in the application of new energy electric vehicles.
