摘要
主要介绍了直接转矩控制和矢量控制在永磁同步电机控制中的区别,同时简要介绍了直接转矩控制的原理,并搭建了永磁同步电机的数学模型,在此基础上借用MTALB的Simulink搭建直接转矩控制永磁同步电机的模型。从仿真结果可以看出,永磁同步电机直接转矩控制时具有良好的转矩响应速度,转速波动小,能够较好地抑制转矩脉动,基本实现了对永磁同步电机的稳定快速控制。
This paper introduces the difference between direct torque control and vector control in permanent magnet synchronous motor control, briefly introduces the principle of direct torque control, and builds the mathematical model of permanent magnet synchronous motor. On this basis, the model of direct torque control permanent magnet synchronous motor is built by using the Simulink of MTALB. The simulation results show that the direct torque control of permanent magnet synchronous motor has good torque response speed, small speed fluctuation, can better suppress torque ripple, and can basically realize the stable and fast control of permanent magnet synchronous motor.
