永磁同步电机SVPWM仿真研究

Simulation Research on PMSM Control System Based on SVPWM Technique

介绍了永磁同步电动机的数学模型和基于id*=0的空间矢量控制(SVPWM)原理,并在S imu link环境下构建了基于SVPWM的永磁同步电机控制系统的仿真模型,最后对整个系统进行了仿真实验研究.仿真结果表明,单位定子电流可实现d-q轴解耦,并可获得最大的电磁转矩,控制系统简单,转矩特性好,可以获得很宽的调速范围.

The principle of the permanent magnet synchronous motor SVPWM control system based on the i^＊d = 0 is set forth in brief, and the simulation model of PMSM control system based on SVPWM is built in Simulink. The analyses show that the parameters in d and q axe are decoupling, the torque control characteristic is finear, output torque is steady, the speed range is wide when the vector control technique is applied in motion control system.
