Design of Robust Chattering free Integral Sliding Mode Controller for Dual Input Buck Boost Converter

摘要

This paper proposes the application of modified Integral sliding mode control (ISMC), replacing the discontinuous part of control with continuous control for the output voltage regulation for dual input buck boost converter (DIBB). The design method is clearly illustrated for dual input buck boost converter with above control strategy. The simulation results reveal the reduction of settling time and chattering in the output of DIBB. The simulation results of DIBB for its responses to load and line regulations with modified ISMC are compared with the simulation results of discontinuous control in ISMC. The results show the effectiveness of modified integral sliding mode control with super-twisting algorithm as continuous part in ISMC.
