线性周期时滞微分方程的特征矩阵

Characteristic matrices for linear periodic delay differential equations

Jan Sieber, Robert Szalai

摘要:

Szalai等人(SIAM J. on Sci. Comp.28(4),2006)给出了周期系数线性时滞微分方程系统特征矩阵的一般构造方法。首先,我们表明,以这种方式构造的矩阵可以有一个离散集极点在复平面,这可能会阻碍他们使用时,确定的稳定性的线性系。然后,我们修改和推广原来的建设,使极点被推入一个小的邻域的原点的复平面。

英文摘要:

Szalai et al. (SIAM J. on Sci. Comp. 28(4), 2006) gave a general construction for characteristic matrices for systems of linear delay-differential equations with periodic coefficients. First, we show that matrices constructed in this way can have a discrete set of poles in the complex plane, which may possibly obstruct their use when determining the stability of the linear system. Then we modify and generalize the original construction such that the poles get pushed into a small neighborhood of the origin of the complex plane.
