非线性PWM反馈时滞系统的稳定性分析

Analysis of the Stability for Nonlinear PWM Feedback Time-delay System

在借鉴前辈学者们的研究基础上,探讨了非线性PWM反馈时滞系统的稳定性;基于PWM(脉冲宽度调制)调控,利用改进的Lyapunov-Krasovskii泛函构造方法来构造V函数,然后通过使用线性矩阵不等式,得到了关于非线性PWM反馈时滞系统指数p次方稳定和指数p次方渐进稳定的判定.

Based on the previous researches, this paper discusses the stability of nonlinear PWM （ Pulse Width Modulation） feedback time-delay system, uses the improved Lyapunov-Krasovskii functional construction method to construct V function, and then obtains the discrimination on pth moment exponential stability and pth moment exponential asymptotic stability of nonlinear PWM feedback time-delay system by using linear matrix inequalities.
