对时滞单输入振动控制系统的部分极点配置问题作了分析和探讨,提出了求解时滞多输入振动控制系统部分极点配置问题的多步法,将不“想要”的特征值配置到给定特征值,其余特征对保持不变,这种方法很容易编程实现而且不需要利用动柔度矩阵或求解Sylvester方程。最后,数值实验的结果表明多步法是有效的。
Abstract
Part of pole points allocation problem of a single-input vibration control system with time-delay was studied. A multi-step method for solving the similar problem of a multi-input vibration control system was proposed, the unwanted eigenvalues were changed into the given ones and all other eigen-pairs kept unchanged. This method was easy to be programmed and implemented, it didn’t need to use a dynamic flexibility matrix or solve Sylvester equation. Numerical examples showed that the multi-step method is effective.
