A Super-Twisting algorithm of robust high order sliding mode control for full-bridge inverter

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 eliminating 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 preliminarily 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.
