摘要： 文章以单相电压型逆变器为研究对象，给出了一种逆变器双环控制策略。首先，基于单相电压型逆变器的主拓扑结构，建立了相应的数学模型，同时建立了逆变器传递函数框图。其次，给出了相应的双环控制结构，该结构为内、外环均为比例控制。在此基础上，采用极点配置法设计了相应的控制参数取值范围。实验结果表明，文章所给的双环控制方法具有较好的动态控制响应和稳态控制性能。

Abstract: This paper taking the single-phase voltage inverter as the research object, an dual-loop control strategy is given. First of all, based on the main topology structure of single-phase voltage source inverter, mathematical model of the inverter is established, at the same time, transfer function block diagram is established. Then, giving the corresponding dual loop control structure, the structure for the inner and outer loop is proportional control. On above basis, the pole assignment method is used to design the control parameters. The experimental results show that the dual-loop control method has good dynamic response and steady state control performance.
