主要研究了具有变时滞的退化时滞微分系统的稳定性.利用退化时滞微分系统的变易公式和Gronwall—Bellman积分不等式给出了该系统的指激估计以及稳定和指数渐近稳定的充分条件.
In this paper, we discussed the stability of degenerate differential systems with variable delay. By using variation formula and Gronwall-Belhnan integral inequality, the exponential estimation of the solution and the sufficient conditions of stability and exponential asymptotic stability for degenerate differential systems with variable delay are obtained.
