摘要
阐述一种基于模糊PI控制的三电平双向DC/DC变换器的均压补偿环结构,分析模糊PI控制器的架构,建立全面有效的规则库,实现均压补偿环结构的模糊PI参数的修正.利用Matlab/Simulink平台构建的仿真系统进行测试,结果表明,改进的控制策略能够快速、稳定实现对母线分压电容的均压控制.
Abstract
This paper describes the voltage equalization compensation loop structure of a three-level bidirectional DC/DC converter based on fuzzy PI control,analyzes the architecture of the fuzzy PI controller,establishes a comprehensive and effective rule library,and realizes the correction of the fuzzy PI parameters of the voltage equalization compensation loop structure.It was tested using a simulation system built on the Matlab/Simulink platform,and the results showed that the improved control strategy can quickly and stably achieve voltage equalization control of the bus divider capacitor.
