根据时标特点—统一连续分析和离散分析,考虑时标上的一类具有正负系数的中立型时滞动力方程的稳定性问题。运用时标的微积分基本理论和Cauchy-Schwarz等重要不等式,避免构造Lyapunov函数的复杂性,利用3/2稳定性的方法,获得该系统一致稳定性及渐近稳定性的充分条件,所得结论统一并包含了已有成果。
According to the characteristics of the time scales-uniform continuous analysis and discrete analysis,consider the stability of neutral delay dynamic equations with positive and negative coefficients on time scales.When using the basic theory underlying calculus of time scalars,Cauchy-Schwarz inequality,the method of 3/2 stability and other important to avoid the complexity of construction Lyapunov function,the sufficient conditions for the uniform stability and the asymptotic stability of the system are obtained.The conclusion has been unified and contained the existing results.
