摘　　要：为提高三相电压型PWM整流器(VSR)的抗干扰能力,同时克服其在两相同步旋转(dq)坐标系下存在的结构复杂并具有耦合项等问题,提出了基于静止坐标系(αβ)下的三相电压型PWM整流器的自抗扰控制方案,解决了三相电压型PWM整流器在突加突卸负载时波动过大的问题。最后在Matlab的Simulink环境下搭建了系统仿真模型,得到了系统在突加突卸负载情况下的波形和相关的动态指标,同时与PI控制器控制下的系统动态指标进行对比分析,对所采用控制方案的有效性得到了验证。To improve the anti-interference ability of three-phase voltage source PWM rectifier(VSR),and overcome the problems of complex structure and coupling term in two-phase synchronous rotation(DQ)coordinate system,an active disturbance rejection control scheme of three-phase voltage source PWM rectifier based on the static coordinate system(αβ)was proposed,which solved the problem of excessive fluctuation of three-phase voltage source PWM rectifier when suddenly adding and unloading load.Finally,the system simulation model was built in the Simulink environment of MATLAB,and the effectiveness of the control scheme is verified.
