In the theory of stability for large - scale systems there are mainly two kinds of analysis approaches 分析大系統(tǒng)穩(wěn)定性的方法主要是李雅普諾夫函數(shù)法。
The theory of stability is a basic and important subject in the theories of differential equations 穩(wěn)定性理論是微分方程理論研究中一個基本而又重要的研究課題。
After considering the nonlinear differential equation with coefficient perturbation , we have obtained the theorem which guarantees the existence of the unique uniformly stable almost periodic solution for the system by using exponential dichotomy and theories of stability 摘要考慮具系數(shù)擾動的非線性微分方程,利用指數(shù)型二分性及穩(wěn)定性有關理論得到了該系統(tǒng)的概周期解的存在性、唯一性和穩(wěn)定性,獲得了一些新的結果。
Linear matrix inequality was introduced to cope with the puzzle of determining common positive matrix . theory of stability analysis and controller design was established based on lmi method . ( 3 ) nonlinear fuzzy p redictive c ontrol t heory b ased on t - s s tate s pace m odel was explored 針對穩(wěn)定性分析中公共正定矩陣p難以確定的難題,引入了lmi方法,借助于成熟的數(shù)學工具,不僅解決了確定公共正定矩陣p的問題,而且建立了基于lmi方法的穩(wěn)定性分析和控制器設計的理論方法。
