MPC based Sliding Mode Control for More Electric Aircraft application

This paper deals with the control of a bidirectional DC/DC converter in the framework of the More Electric Aircraft (MEA). The objective is to regulate the power flow between the aeronautical main generator and a battery connected to the grid through the bidirectional converter. The proposed control strategy comprises of a hierarchical control consisting of a fixed time Second Order Sliding Mode Control layer driven by a nonlinear Model Predictive Control strategy. The current entering (or exiting) the bidirectional converter on the network side is regulated by adaptively controlling the converter current on the battery side. Detailed simulations have been provided in order to verify the effectiveness of the proposed control strategy.
