Summary In this paper, a sliding manifold‐based control strategy is used for controlling a bidirectional DC‐DC converter for aeronautic applications. The proposed design follows a 2‐level strategy, where low‐level controllers are designed first, then a high‐level supervisor is used for scheduling the low‐level controllers. Different from previous approaches, each of the low‐level controlled system is a globally exponentially stable closed‐loop system, thus resulting into simpler conditions for the stability of the overall system. Moreover, stability of the supervisory strategy is rigorously proved by using a suitable Lyapunov function. Finally, a switching implementation is also considered. The effectiveness and robustness of the proposed strategy is shown by detailed simulations in Matlab/Stateflow/SymPowerSystem.
