摘要
针对内置式永磁同步电机(IPMSM,Interior Permanent Magnet Synchronous Motor),在转子同步旋转坐标系下的数学模型进行了分析,提出了一种最大转矩电流比(MTPA,maximum torque per ampere)控制策略,以减小逆变器容量,同时采用SVPWM算法以减小转矩脉动。最后在MATLAB/Simulink环境下分别采用MTPA控制和id=0控制,对两种方法进行仿真并比较,仿真结果验证了所采用算法的有效性。
Based on the mathematical model of interior permanent magnet synchronous motor in the rotor coordinate system which rotates synchronously, the MTPA control is presented to minimize the inverter capacity. And the algorithm of SVPWM is used to reduce the torque ripple. Finally, the simulation of the MTPA control and the id = 0 control is carried out in the Simulink and the simulation results show the feasibility of the MTPA control.
