摘　　要：在逆变器控制方式研究的基础上,提出了一种逆变器的变结构复合控制方法。对单相全桥逆变器的滑模控制及电压滞环控制的方式进行了分析,利用两种控制方式的优势互补,将逆变器的滑模控制与PI+电压滞环控制相结合用于提高系统的控制性能。仿真结果表明,该方案具有较高的控制精度及良好的动态跟踪性和鲁棒性,并验证了方案的可行性。A kind of compound control method with structure changes is suggested on the inverter. A sliding mode control method and the voltage hysteresis scheme for the full bridge inverter are analyzed respectively,and inter-complementation of advantages of control modes of two typesthe combination of sliding mode control with PI＋votage hysteresis is applied to the improvement of the system control performances. Simulation results show that the suggested scheme is of high control accuracy and fast dynamic response and strong robustness, and certificate the feasibility of schame.
