Abstract: Using the theories and methods of sliding mode control, the variable structure controllers are designed to control chaos in DC-DC Buck converter by means of direct and indirect control. Some desired output voltages are obtained using this control method. The correctness and effect of this method has been confirmed by theoretic analysis and numerical simulation.

Key words: sliding mode control, DC-DC Buck converter, robust
