摘　　要：针对基于单一控制的单相全桥逆变器存在稳定性和鲁棒性较差的问题,提出了一种基于迭代学习控制和模糊PI控制的复合控制策略。模糊PI控制用来提高单相全桥逆变器的动态特性,迭代学习控制用来改善单相全桥逆变器的稳态精度。仿真结果表明,基于复合控制策略的单相全桥逆变器输出电压波形畸变率小,动态响应快,稳态精度高。In view of problems of bad reliability and robustness existed in single-phase full-bridge inverter based on single control, the paper proposed a compound control strategy based on iterative learning control and fuzzy PI control. The fuzzy PI control is used to improve dynamic characteristics of the inverter, and the iterative learning control is used to improve steady precision of the inverter. The simulation result shows that waveform of output voltage of the inverter based on compound control strategy has low distortion rate, fast dynamic response and high steady precision.
