摘　　要：根据混合励磁同步电机的特点,结合空间电压矢量控制算法,提出了一种在额定转速及以下时增大输出力矩的新型控制策略,同时对如何有效增磁以实现低速大力矩的控制算法进行了深入的研究。该控制思想是把电机控制分为常规力矩区与动态增磁区,在不同的区域下采用不同的控制方法,使得电机在整个运行中能表现出良好的动态性能。实验结果表明,所提出的控制策略,能够有效实现电机在额定转速以下力矩大幅的增加,且电机运行稳定,动态性能良好。In this paper ,according to the characteristics of hybrid excitation synchronous motor ,combining space voltage vector control algorithm , put forward a novel motor control strategy which could increase output torque at rated speed and below . Meanwhile ,the effective magnet-increasing method to realize the control algorithm of low speed and high torque is investigated .The control idea is that the motor control is divided into conventional torque zone and dynamic enhanced magnetic zone .In different zones ,using different control methods , the motor can exhibit good dynamic performance in the entire operation . Experimental results show that the proposed control strategy can effectively achieve the motor torque substantial increasing at rated speed and below ,and the motor runs stable ,having good dynamic performance .
