断续导电模式Buck变换器的逆系统最优控制
Inverse System Optimal Control for Buck Converter in Discontinuous Conduction Mode
摘要
Abstract
An inverse system optimal control strategy is proposed for Buck converter in discontinuous conduction mode(DCM).A non-linear mathematical model of the DCM Buck converter is established.The reversibility of the model is analyzed based on the inverse sys-tem theory,exact feedback linearization is implemented,and its pseudo linear system is obtained.Furthermore,the optimal controller de-sign for pseudo linear systems is carried out,the selection of optimal control parameters is discussed,and the selection rules are provid-ed.Finally,a prototype of the proposed control strategy is constructed for relevant experiments.The experimental results verify the cor-rectness and effectiveness of the proposed control strategy.关键词
