Safdar Qureshi . Feedback and Sliding Mode Control of D.C.-D.C.Converters. National Conference on Innovations and Recent Trends in Engineering and Technology. NCIRET, 3 (November 2014), 31-34.
The Performance of DC-DC converters with voltage, current and voltage cum current feedback controllers greatly improve their utility. Several integrated circuits are commercially available to provide linear feedback in dc-dc converters. Because of inherent nonlinearity of converters, linear feedback circuits provide good performance over a narrow range of variations of their parameters. Sliding mode controller is a nonlinear controller that can provide good performance over a wide range of variation of parameters. It is a robust controller especially suitable for variable structure systems like a converter. Example of design of a sliding mode controller for a dc-dc buck converter has been illustrated. A detailed list of references for advanced studies in this field is appended.
