摘要
随着永磁材料的发现和现代电机控制技术的不断发展,三相永磁同步电机的控制方式逐渐演变为矢量控制和直接转矩控制两大流派,并各有千秋。矢量控制和直接转矩控制虽然在控制系统组成、控制过程、形式以及效果等方面存在差异,但是2种控制方式拥有相同的理论基础,控制本质是一致的。通过Matlab/Simulink软件仿真和转矩公式分析进行了验证。
With the discovery of permanent magnet materials and the continuous development of modern motor control technology,the control mode of three-phase permanent magnet synchronous motors has gradually evolved into two schools:vector control and direct torque control and either has its own advantages and disadvantages.Although there are differences between the two control modes in control system composition,control process,form and effect,both control modes have the same theoretical basis,and their nature is the same.It is verified by Matlab/Simulink software simulation and torque formula analysis.
