摘　　要：针对传统的永磁同步电机直接转矩控制(DTC)系统抗干扰性差、开关频率不稳定以及磁链脉动大的问题,在基于开关表的直接转矩控制方法上进行改进,引进空间电压矢量脉宽调制技术(SVPWM)和自抗扰控制技术(ADRC)。仿真结果显示:加入了自抗扰控制器以及空间电压矢量脉宽调制技术的永磁同步电机直接转矩控制系统转矩脉动明显减小,系统抗干扰性增强,开关频率更加稳定。To deal with problem in the traditional permanent magnet synchronous motor(PMSM)direct torque control(DTC)system,such as poor immunity,the switching frequency instability and the big flux ripple,the direct torque control based on the switch table was improved,space vector pulse width modulation(SVPWM)and auto disturbances rejection contro(l ADRC)technology were led in.The simulation results based on Matlab/Simulink show to us:with the auto disturbances rejection control(ADRC)and space vector pulse width modulation(SVPWM),the flux pulsation of permanent magnet synchronous moto(r PMSM)direct torque contro(l DTC)system is significantly reduced,the anti-jamming of this system is obviously enhanced,and the switching frequency is more stable.
