摘要
将空间矢量脉宽调制技术(SVPWM)引入到了永磁同步电机的直接转矩控制(DTC)当中,实现了电压空间矢量的连续调节。定子磁链近似为圆形,有效地解决了常规DTC系统电磁转矩脉动较大的问题。在MATLAB/Simulink环境下搭建了永磁同步电机基于SVPWM的直接转矩控制系统的模型,对电机的多种运行状态进行了仿真,验证了控制理论的正确性和有效性。
SVPWM is bought into PMSM DTC system in the paper.Continuous adjustment of space voltage vector is realized.The obvious ripples in the conventional DTC system are reduced effectively because of the circular stator flux.Models of DTC based on SVPWM are built in MATLAB/Simulink.A variety of motor running states are simulated, which verifies the validity and the correctness of the control strategy.
