针对双三相永磁同步电机（PMSM）矢量控制系统中定子相电流的谐波问题，在采用传统两矢量空间矢量脉宽调制算法的基础上，提出基于最大四矢量的空间矢量脉宽调制算法的磁场定向控制策略。其次，针对最大四矢量的空间矢量脉宽调制算法计算量大，设计复杂的问题，又提出了基于虚拟电压矢量的空间矢量脉宽调制算法的改进型磁场定向控制策略。最后，通过MATLAB/Simulink仿真平台，验证所提出的改进型控制算法策略的有效性。

Aiming at the harmonic problem of stator phase current in the vector control system of a dual three-phase permanent magnet synchronous motor (PMSM), a magnetic field oriented control strategy based on the space vector pulse width modulation (SVPWM) algorithm with the maximum four-vector is proposed on the basis of using a conventional two-vector SVPWM algorithm. Secondly, to solve the problem of large computation and complex design of the SVPWM algorithm with maximum four vectors, an improved magnetic field oriented control strategy based on the SVPWM algorithm with virtual voltage vector is proposed. Finally, the effectiveness of the proposed improved control algorithm strategy is verified by MATLAB/Simulink simulation platform.
