双环控制外环为电压环，而内环则分为电感电流内环和电容电流内环。在此对这俩种方法的不同之处进行了理论分析，为了改善该种控制系统在抗负载扰动方面的不足，在双环控制的基础上引入了负载电流前馈的设置。通过负载电流前馈控制的设置，有效地提高了该种控制抗负载的扰动性能，从而增强了系统的稳定性和改善了逆变器电压输出波形质量。

The outer?ring of the double?ring control system is voltage ring,and its inner ring is divided into inductance cur?rent inner?ring and capacitive current inner?ring. The difference between the two kinds of methods is analyzed theoretically in this paper. On the basis of the double?ring control,a load current feed?forward setup is introduced to improve the performance of the control system effectively in the aspect of resistance to load disturbance. With the load current feed?forward control setup, the stability of the system was enhanced and the quality of inverter output voltage waveform was improved.
