利用高阶滑模super?twisting算法设计一种全桥逆变电路的控制器。该算法的核心思想是将离散控制律转移至更高阶的滑模面，从本质上消除一介滑模的抖颤影响。为了验证算法的可行性和有效性，利用MATLAB仿真软件对控制系统进行了对比实验，结果表明：1）在稳态性能下，相比于典型PI控制高阶滑模控制具有更好的跟踪效果。2）在输入和负载的扰动情况下，高阶滑模控制显示出强鲁棒性，对输入和负载的扰动不敏感。

Based on Super?Twisting algorithm of high order sliding mode, this paper designs a controller of full bridge inverter. The core idea is to transfer the discrete control law to high order sliding manifold, essentially elimi?nating the impact of chattering effect. In order to justify the feasibility and effectiveness of the algorithm, it uses MATLAB to simulate control systems and compare results. The simulation results and their analysis show prelimina?rily that:(1) under the steady state condition, compared with the typical PI control, the high order sliding mode has better tracking;(2) under the condition of large disturbances in input and output, the high order sliding mode control shows strong robustness to the input and output disturbances.
