Analysis of Passivity-based Sliding-mode Control Strategy in DC-DC converter

In order to overcome the deficiency of sliding-mode control or passivity-based control alone, passivity-based sliding-mode strategy is proposed for buck converter in this paper. This strategy can not only solve the chattering problems in sliding mode control, but also reduce overshoot and the long settling time of current problem in passivity-based control. Simulation results demonstrate the effectiveness of this strategy.
