提出了一种电动汽车用混合励磁同步电动机的最优电流控制方法。该控制旨在满足转矩和速度要求，同时确保最小的铜和铁损耗。扩展的拉格朗日乘子优化方法（库恩-塔克条件）被用来详细说明最佳参考电枢电流的解析表达式，以及为磁场电流，如果相对于电枢电流和电压的约束。在新的欧洲驱动周期的仿真证明，所提出的最优控制导致最低的损失相比，由其他同步电机控制策略所获得的结果。
This paper presents an optimal current control for the hybrid excitation synchronous motor in electric vehicle application. The control aims to meet the torque and speed requirements while insuring minimal copper and iron losses. Extended Lagrange multipliers optimization method (Kuhn-Tucker conditions) is used to elaborate analytical expressions for the optimal reference armature currents as well as for the field current if with respect to armature current and voltage constraints. Simulation over the new European driving cycle proves that the proposed optimal control leads to the lowest losses compared to the results obtained by other synchronous motor control strategies.
