Sliding mode control of boost and buck-boost power converters using method of stable system centre.
Nonminimum phase direct tracking control of voltage is studied for boost and buck-boost power converters. The nonminimum phase output tracking problem is reduced to a state tracking problem. Bounded state tracking profiles are generated by equations of stable system centre. As shown in the paper, for both converters, the sliding mode control design provides high accuracy tracking a voltage reference profile given by an exogenous system in real time. The effectiveness of the sliding mode control design is demonstrated by numerical examples.
