摘要 单电流调节器弱磁控制是一种有效的永磁同步电机弱磁控制策略,该控制方法只需要一个电流调节器就可以同时实现速度调节和弱磁控制,结构简单、动态响应快,并且能够解决传统弱磁控制策略中双电流调节器在电机高速时易于饱和的问题,但是电机不能充分利用逆变器输出电压,且电机的带载能力和效率不能兼顾。该文提出基于虚拟电阻的单电流调节器弱磁控制策略,对单电流调节器弱磁控制中的弱磁电压依据电流轨迹进行优化设计,在保证动态调速性能和带载能力的同时实现效率优化;构建基于虚拟电阻的单电流调节器弱磁控制系统,通过仿真和实验验证了该算法的正确性和有效性。

Abstract:The flux-weakening control scheme with one single current regulator has the advantage of simplicity and fast dynamic response, which is a competitive candidate in practice for control of permanent magnet synchronous motors (PMSM). Besides, it can effectively avoid the saturation issue of the traditional flux weakening control scheme with two current regulators when the PMSM runs at very high speed. Despite these advantages, it cannot fully use the output voltage of the motor, and high loading capacity and high efficiency are difficult to be realized simultaneously. To overcome the drawback, a single current regulator based on virtual resistor is proposed in this paper to realize the flux-weakening control, which achieves the ability of high dynamic response, high efficiency, and high loading capacity at the same time. Eventually, simulation and experimental results validate the effectiveness of the proposed control strategy.
