Resumo

This paper presents the design and evaluation of a robust controller, based on linear programming, Kharitonov’s theorem and Chebyshev’s theorem, in order to regulate the output voltage of the Dual Active Bridge (DAB) converter under parametric uncertainties. These robust control approach take into account all possible uncertainties in the system such as load and input voltage variations, improving the system performance. The converter is controlled by single phase-shift-modulation (PSM) with a fixed duty cycle. The proposed controller ensures robust control performance and stability with a minor performance degradation compared to an interval robust controller and a conventional controller. Simulation results are presented to validate the robustness and effectiveness of the proposed controller.
