Generalized Super-Twisting control of a Dual Active Bridge for More Electric Aircraft

In this work the control of a Dual Active Bridge (DAB) is presented. The application is within the innovative framework of the More Electric Aircraft (MEA) concept, and its goal is to recharge a battery pack in the case of standard loading conditions, while using the batteries to supply energy to an extra-load in the case of overload. The control objective is achieved through the adoption of the Generalized Super-Twisting algorithm. Rigorous mathematical proofs of stability are given for the controlled system and for supervisor switching between normal condition and overload. The effectiveness of the proposed strategy is shown by detailed simulations in Matlab/Stateflow/Electronics.
