摘　　要：首先运用状态空间法建立基于超级电容的双向DC/DC变换器Buck电路模式的数学模型,应用开关周期平均值以及欧拉公式对其进行分析,并引入小信号扰动,分离扰动并线性化后设计出Buck电路模型的控制方法—双闭环控制策略。最后搭建Simulink仿真以验证控制策略的有效性与正确性,其结果为超级电容的应用和研究提供参考。First of all, the state space method is adopted to establish the super capacitor two-way Buck DC/DC con- verter circuit model, and the switch cycle average value and Euler formula are applied to analyze mathematical model, and the small signal disturbance is introduced, and the control method of Buck circuit model-the double closed loop control strategy is designed after the disturbance separation and linearization. Finally, Simulink simulation is built to verify the correctness and feasibility of the control strategy, and the results provide reference to apply and research for super capacitor.
