Abstract
This paper deals with the problem of controlling of interleaved boost power converter for fuel cell generation system. The proposed nonlinear adaptive controller is designed using the backstepping technique, based on the whole nonlinear system model that accounts for the Boost converter dynamics and the fuel cell nonlinear characteristic. The adaptive nonlinear controller involves an online estimation of unknown load resistance which represents the uncertainty of the power in DC bus. The control objective is three folds: (i) asymptotic stability of the closed loop system, (ii) perfect output voltage regulation under uncertainty and finally (iii) good current sharing between modules. It is formally shown, using a theoretical analysis and simulation results that the proposed control meets all objectives.
