Robust control of an interleaved DC-DC buck converter with coupled inductors

This paper introduces a novel adaptive and robust control methodology for an interleaved DC-DC buck converter with coupled inductors. Initially, a dynamical average model of the system is presented. Subsequently, a robust adaptive controller is developed, ensuring stable voltage reference tracking in the presence of system uncertainties. The controller design employs a multi-step approach, utilizing a back-stepping controller. The effectiveness of the proposed controller is evaluated through MATLAB/Simulink simulations and a Plexim RT-Box hardware-in-the-loop implementation.
