本文对一类包含许多不同 DC-DC 转换器的脉宽调制 (PWM) 系统进行了稳定性分析。考虑两种类型的脉宽调制（数字和模拟控制）。开发了一个用于系统搜索李亚普诺夫函数的程序。状态空间的划分方式是，如果一组耦合线性矩阵不等式 (LMI) 可行，则可以验证稳定性。考虑全局稳定性以及局部吸引力区域的计算。
The paper presents stability analysis of a class of pulse-width modulated (PWM) systems which incorporates many different DC-DC converters. Two types of pulse-width modulation (digital and analog control) are considered. A procedure is developed for systematic search for Lyapunov functions. The state space is partitioned in such a way that stability is verified if a set of coupled linear matrix inequalities (LMIs) is feasible. Global stability is considered as well as the computation of local regions of attraction.
