摘要
简要综述了迭代法在时滞系统稳定性与Hopf分岔研究中的若干新进展。在稳定性分析中,利用Lambert W函数,时滞系统的最大实部特征根可以用Newton-Raphson等迭代法求得。而在Hopf分岔分析中,利用迭代法求得了分岔周期解的近似表达式。对这两个问题,迭代法简便有效。
This paper presents a brief review on the recent advances in applications of iterative methods to studies on stability and Hopf bifurcation of time-delay systems. In stability analysis, the Newton-Raphson iterative method is used to calculate the rightmost characteristic root(s), with the help of the Lambert W function. In Hopf bifurcation analysis, the iterative method is applied for finding an approximate solution of the bifurcated periodic solution. In both cases, the iterative methods are very effective.
