摘要：分析了全桥型逆变器的滑模控制方案，包括:建立系统的变结构模型、选择滑模切换面和确定控制律、给出可到达条件及滑模存在区域等。着重讨论了滑模控制器设计中切换面系数和切换频率的选择原则，并在此基础上利用Matlab进行了仿真研究。仿真结果表明，该滑模控制全桥型逆变器的输出电压能够快速跟踪参考信号，并且表现出了较强的鲁棒性以及良好的动态特性。

Abstract: A sliding mode control scheme for the full bridge buck inverter was analyzed, including modeling the variable structure system, selecting the switching surface and control law, and deriving reaching conditions and sliding domain. The criterions of selecting switching surface coefficients and switching frequency for sliding mode controller design were considered. Simulations were carried out by Matlab according to it. The simulations results show that the output voltage of the sliding mode control inverter tracks the reference sinusoidal signal fast, and the inverter exhibits good dynamic property and robustness.
Key words: inverter; sliding mode variable structure control (SMVSC); robustness; Matlab simulation
