Terminal sliding mode control for buck converter with chaos

Abstract

Buck converter is a high non-linear system, which can produce chaotic phenomenon under certain parameters. So the paper studied the phenomena and mechanism of chaos generated in it firstly, simulation results show the existence of chaos in buck converter. Then a simple and effective nonlinear control— sliding mode control method was proposed for buck converter to control the chaotic behavior. The simulation results verified the effectiveness and correctness of the proposed strategy.
