摘　　要：随着逆变器在众多领域越来越重要,而传统的电压电流双闭环控制波形质量和响应速度不高,因此本文对传统方法进行改进,提出了一种新型控制方法,即不需要电感L准确值的电流解耦控制和采用模糊算法设计电压环来实现对输出电压控的稳定控制。并用MATLAB SIMLIMNK进行仿真建模,实验结果表明此控制策略电压输出波形比较稳定。With inverter is more and more impnrtant in many areas, the traditional voltage current double chosed loop control waveform quality and speed of response is not high, so to improve the traditional method, this paper proposes a new control method, which does not need the induetanee L accurale value of current deeoupling control and fuzzy algorithm design voltage loop to achieve the stability control of the output voltage control. With MATLAB SIMLIMNK simulation modeling, experiment results show that the control strategy of voltage output waveform is stable.
