线性时滞系统的正型与稳定性

Positive Forms and Stability of Linear Time-Delay Systems

Matthew M. Peet, Antonis Papachristodoulou, Sanjay Lall

摘要:

考虑了线性时滞微分方程的李雅普诺夫函数的构造问题。对于这样的系统,它是已知的,指数稳定性意味着存在一个积极的李雅普诺夫函数,这是二次空间上的连续函数。利用正半定矩阵给出了正李雅普诺夫函数锥的有限维子集序列的显式参数化。这使得线性时滞系统的稳定性分析可以用半定规划的形式来表示。

英文摘要:

We consider the problem of constructing Lyapunov functions for linear differential equations with delays. For such systems it is known that exponential stability implies the existence of a positive Lyapunov function which is quadratic on the space of continuous functions. We give an explicit parametrization of a sequence of finite-dimensional subsets of the cone of positive Lyapunov functions using positive semidefinite matrices. This allows stability analysis of linear time-delay systems to be formulated as a semidefinite program.
