Abstract
This paper presents a novel robust adaptive Proportional-Integral (PI) controller for a Dual Active Bridge (DAB) converter, enhanced through Transfer Learning and the Snake Optimization algorithm. The DAB converter exhibits complex nonlinear dynamics due to its bidirectional power flow, high-frequency operation, and resonant elements, posing significant challenges for conventional control strategies. To address these challenges, a flexible and adaptive control framework is developed that dynamically adjusts to variations in operating conditions and system parameters. The proposed controller combines an adaptive PI structure with Transfer Learning (TL) to utilize previously acquired control knowledge for improving learning efficiency and robustness across different scenarios. The Snake Optimization Algorithm (SOA) is employed to fine-tune the controller gains, ensuring superior transient performance and minimal steady-state error. Simulation results under diverse conditions - including parameter uncertainties and load changes - demonstrate the effectiveness of the method. Furthermore, experimental validation using a Hardware-in-Loop (HIL) setup confirms the real-time feasibility and performance of the proposed control strategy in managing the complex dynamics of the DAB converter.
