基于离散演化映射的DC/DC变换器混合逻辑动态建模
Mixed logical dynamical modeling of DC/DC converter based on discrete evolution mapping
摘要
Abstract
A novel dynamical modeling method, namely, the mixed logical dynamical model ( MLD) based on dis-crete evolution mapping theory by integrating the Hamilton′s principle and hybrid system theory, for DC/DC converter has been proposed.In this paper, without loss of generality, the mixed logical dynamical ( MLD) modeling of Buck converter is achieved by unifying the discrete evolution mapping model, which is obtained by variational integrators, in continuous current mode ( CCM) and discontinuous current mode ( DCM) under the hybrid system theory frame-work.The simulation result shows that the new model has many advantages, such as less calculation needed, high precision and it can completely describe the various working states of the system and reflects dynamical characteristics of inductor current ripple etc, over those conventional ways, which means this novel model could be more useful for a-nalysis and controller designing of DC/DC converters.关键词
