Buck型变换器预设时间自适应反演控制
Predefined-time adaptive backstepping control for Buck converter
摘要
Abstract
A predefined-time adaptive backstepping control scheme is proposed for Buck converter system aiming at load variation and external interference,which provides the direct relationship between system's adjustable time and control parameters.It reduces the complexity of parameter setting.To avoid the singularity problem caused by the differential of the virtual controller,a quadratic fractional virtual controller is constructed to ensure that the output voltage converges to the reference voltage adjacency region within a predefined time.Finally,the simulation and experimental results show the effectiveness of the proposed control scheme.关键词
