利用比较原理结合向量Lyapunov函数研究一类多滞后线性时变系统的不稳定性,并在此基础上进一步研究一类多滞后非线性系统及多滞后区间系数系统的不稳定性。给出相关定理,丰富已有文献的相应结果。
In order to investigate the instability of a class of linear time-varying systems with multidelays, the comparison principle with the vector Lyapunov function is employed. Based on the same technique, we also study the instability of a class of multidelay nonlinear systems and interval coefficient continuous systems with multidelays. The results obtained in this paper extend some existing achievements in this subject.
