摘　　要：针对传统的比例积分(proportional integral,PI)控制器在双三相永磁同步电机(dual three-phase permanent magnet synchronous motor,DTP-PMSM)的四维矢量控制系统中存在响应速度慢及谐波电流大的问题,本文提出一种基于准比例谐振(quasi-proportional resonance,Q-PR)控制器的DTP-PMSM控制策略,通过使用矢量空间解耦方法对DTP-PMSM进行建模,在基波子平面的电流环中使用PI控制器控制,同时在谐波子空间引入准比例谐振控制器,抑制5、7次谐波电流对电动机运行的影响。仿真结果表明,Q-PR控制器相较于传统PI控制器,在谐波抑制方面具有一定优化效果。In order to solve the problems of slow response speed and large harmonic current in the vector control system of dual three-phase permanent magnet synchronous motor(DTP-PMSM)in the traditional proportional integral controller,this paper proposes a DTP-PMSM control strategy based on quasi-proportional resonant controller.It uses the vector space decoupling method to model DTP-PMSM,and uses the PI controller to control the current loop of the fundamental subplane,and introduces a proportional resonant controller into the harmonic subspace to suppress the influence of the 5th and 7th harmonic current on the operation of the motor.The simulation results show that Q-PR controller has certain optimization effect in harmonic suppression compared with traditional PI controller.
