研究了含有时变时滞的不确定中立系统的时滞相关稳定性问题.假定不确定参数是范数有界的,通过构造新的Lyapunov泛函和使用更一般的时滞分解方法,得到了基于LMI新颖的时滞相关稳定条件,并且用Matlab LMI工具箱很容易地求解.数值实例表明本文方法所得结果优于现有文献中的结果.
In this paper,the delay-dependent stability problem is investigated for uncertain neutral systems with time-varying delays.The parameter uncertainties are assumed to be norm-bounded. By constructing a new Lyapunov functional and by making use of more general delay decomposition approach,some novel delay-dependent stability criteria for the system are obtained as a set of LMIs(linear matrix inequalities),which can be readily solved by using the Matlab LMI toolbox. Numerical examples show that the results obtained in this paper are better than existing results.
