摘　　要：文章针对光伏发电系统中的Boost型DC-DC变换器,提出了一种基于超螺旋算法的复合控制策略。基于超螺旋算法设计电流内环控制器,接着基于超螺旋算法设计干扰观测器估计扰动,基于干扰观测器和PI控制器,设计电压外环复合控制器,该控制策略使得系统具有快响应特性和强抗干扰性能。通过Matlab/Simulink搭建了仿真模型,仿真结果表明,在所提出的复合控制策略作用下,Boost型DC-DC变换器控制系统具有良好的控制性能。This article proposes a composite control strategy based on the hyper spiral algorithm for Boost DC-DC converters in photovoltaic power generation systems.Firstly,a current inner loop controller is designed based on the hyper spiral algorithm.Then,a disturbance observer is designed based on the hyper spiral algorithm to estimate disturbances.Finally,a voltage outer loop composite controller is designed based on the disturbance observer and PI controller.This control strategy enables the system to have fast response characteristics and strong anti-interference performance.Finally,a simulation model was built using Matlab/Simulink,and the simulation results showed that the Boost type DC-DC converter control system had good control performance under the proposed composite control strategy.
