摘　　要：应用Lyapunov等价法讨论了多滞后中立型非线性定常控制系统与不带滞后的线性定常控制系统的镇定问题。应用Lyapunov稳定性理论与Krosovskii最大最小特征值定理,得到了多滞后中立型非线性定常控制系统渐近稳定的结论,该结论是对前人结果的进一步扩展,并在非线性项的限制下给出了时滞的界限。最后,将上述结论推广到了多滞后中立型非线性时变控制系统。By using the Lyapunov stabilization equivalence method, the stabilization problem of nonlinear neutral time-invariant multi-delay control systems and nonlinear time-invariant control systems without timedelay is discussed. By using Lyapunov stability theory and Krosovskki＇s maximum and minimum characteristic value theorem, the conclusion concerning asymptotic stability is obtained for the above nonlinear neutral time-invariant control systems with multi-delay; this conclusion is an expansion of a previous conclusion obtained by other researchers. At the same time, the estimated bound on the time-delay is given under some restriction condition on the nonlinear term. Finally, the above conclusion is extended to nonlinear neutral timevarying control systems with multi-delay.
