摘要

双向DC-DC变换器是一种典型的混合电力储能系统，本文提出了一种针对双向DC-DC变换器的混合控制方法，以获得良好的控制性能。根据能量流的方向，变换器的工作模式分为Buck模式和Boost模式。考虑到双向DC-DC变换器的混合特性，基于混合自动机理论得到了混合自动机。然后将控制算法的设计过程等效为混合自动机的守卫选择问题。根据电路原理，选择保护条件。实验结果表明，该混合控制算法鲁棒性强，计算量小，具有全局稳定性。

Implementation of hybrid control for Bi-directional DC-DC converter

The bi-directional DC-DC converter is a typical hybrid power energy storage system, this paper presents a hybrid control approach for the bi-directional DC-DC converter to achieve a good control performance. The operation mode of the converter is divided into Buck mode and Boost mode according to the direction of energy flow. Considering the hybrid properties of bi-directional DC-DC converter, the hybrid automatons are obtained based on hybrid automaton theory. Then the process of control algorithm design is equivalent to the guard-selection problem of hybrid automaton. Based on the circuit theory, the guard conditions are selected. The experimental results show that the proposed hybrid control algorithm has a high degree of robustness, a low amount of computations as well as a global stability.
