摘要 研究一类带有时滞和非线性不确定性的不确定中立系统的鲁棒稳定性问题.通过选择适当的Lyapunov函数,使用Leibniz-Newton公式的变形,结合自由权矩阵思想,加入一些自由矩阵,并且利用线性矩阵不等式(LMI)技术,得到了新的带有时滞和非线性不确定性的中立系统的时滞依赖稳定性条件.最后,通过数值算例来验证此方法的可行性以及有效性. The problem of robust stability for a class of uncertain neutral system with time-varying delay and non-linear uncertainties is studied. By choosing appropriate Lyapunov function, and using the transform of Leibniz-Newton formulas as well as the free matrics, a new delay-dependent stability criteria is presented by linear matrix in equalities(LMIs) which can be easily solved by LMI Tool box-in Matlab. A numerical example is given to il-lustrate the effectiveness of the developed techniques.
