摘要

本文将DC-DC变换器视为一类混合系统，即开关线性系统。提出了切换线性系统的一种新的数学模型——矩阵系数多项式描述模型。建立了连续变量与离散变量之间关系的一种明显的描述形式，给出了连续变量与离散变量直接相互作用的DC-DC变换器切换线性系统的新模型。该模型在一定程度上有助于揭示运行活动的本质，分析直流-直流变换器的性能。稳态分析和瞬态响应闭环仿真结果均验证了该模型的有效性和实用性

Matrix Coefficient Polynomial Description Model of DC-DC Converters Based on Switched Linear Systems

In this paper, DC-DC converters are viewed as one class of hybrid systems i.e. switched linear systems. A new mathematical model of switched linear systems-matrix coefficient polynomial description model is presented. An obvious description form of the relationship between the continuous variable and discrete variable is built, a new model of switched linear system of DC-DC converters, in which continuous variable and discrete variable interact on each other directly, is given. To some extent, the new model helps to reveal the essence of operation activity and analyze the performance of DC-DC converters. Both the results of steady-state analysis and closed-loop simulation of transient response have verified the validity and practicability of the new model
