基于参数依赖齐次多项式的时变系统稳定性分析
Stability analysis of time-varying systems via parameter-dependent homogeneous Lyapunov functions
摘要
Abstract
This paper considers the stability analysis of linear continuous-time systems and that the dynamic matrices are affected by uncertain time-varying parameters which are assumed to be bounded continuously differentiable with bounded rates of variation. First sufficient conditions of stability for time-varying systems are given by the commonly used parameter-dependent quadratic Lyapunov function. Moreover the use of homogeneous polynomial Lyapunov functions for the stability analysis of the linear system subject to the time-varying parametric uncertainty is introduced. Sufficient conditions to determine the sought after Lyapunov function is derived via a suitable paramenterization of polynomial homogeneous forms. A numerical example is given to illustrate that the stability conditions are less conservative than similar tests in the literature.关键词
