摘要

为提升双有源桥DC-DC变换器在直流微电网发生扰动下的性能

该文针对双有源桥DC-DC变换器动态响应性能与应力优化问题展开研究

并提出一种新型混合控制策略。该策略融合了扩展移相调制和模型预测控制

旨在降低变换器电流应力

并通过优化控制提升动态响应与稳态精度。此外

鉴于模型预测控制对参数的敏感性

引入误差校正方法作为反馈校正环节

以消除因参数失配所引起的稳态误差

从而提高系统的控制精度与系统鲁棒性。仿真与实验均验证了所提控制策略的实用性与优越性。

Abstract

To enhance the performance of the dual-active-bridge DC-DC converter under disturbances in DC microgrids

this paper investigates its dynamic response and current stress optimization. A novel hybrid control strategy is proposed

which integrates extended phase shift modulation with model predictive control （MPC）. This strategy is designed to reduce current stress in the converter and improve both dynamic response and steady-state accuracy through optimized control. Additionally

considering the sensitivity of MPC to parameters

an error correction method is introduced as a feedback correction loop to eliminate steady-state errors caused by parameter mismatches

thereby enhancing control accuracy and system robustness. The results from both simulation and experimentation collectively demonstrate the practicality and advantages of the proposed control strategy.
