文章介绍了永磁同步电机直接转矩控制的原理，分析了传统直接转矩控制系统转矩脉动的缺点，并且将空间矢量脉宽调制技术引入永磁同步电机的直接转矩控制系统中，利用空间矢量的调制过程，可在相同的系统硬件条件下得到更多的、连续的电压空间矢量，进而得到对电机更准确的控制。仿真结果表明，该方案既保持了直接转矩控制快速动态响应，又减小了电机转矩的脉动。

This paper introduces the principle of direct torque control of permanent magnet synchronous motor,dis-cussed the disadvantages of the torque ripple of traditional direct torgue control system,and introduces the space vector pulse width modulation technique into the direct torque control system of permanent magnet synchronous motor.Under the same hardware conditions,the system can obtain more continuous voltage space vector by taking advantage of SVPWM. The simulation results show the program not only keep the direct torque control fast dynamic response,but also reduce the motor torque ripple.
