基于buck变换电路的双闭环超级电容器充电电源，控制器采用PI调节，恒流控制充电，效果良好-Based on buck transform circuit, the double closed loop capacitor charging power supply ，controller PI adjustment, the constant current charge control，The result is good

对实际应用buck电路进行了simulink模型搭建，建立了电流电压双环pid控制，针对模型调参，搭建了buck电路的平均开关模型进行了一键整定。(The Simulink model is built for the practical application of buck circuit, and the current and voltage double loop PID control is established. In order to adjust the parameters
