摘要

基于弹簧时滞反馈控制器，研究了不可扩展欧拉-伯努利梁激励悬臂梁的主共振问题。弹簧控制器设计用于控制非线性动态系统的动态行为。直接采用多尺度法求解线性方程。研究了反馈增益和时滞对稳态响应的影响。研究发现，适当选择反馈增益和时滞可以提高系统的控制性能。可以消除分岔或改变分岔点的位置。

Time-delay control for non-linear dynamic cantilever beam

Based on spring time-delay feedback controller, the excited cantilever beam modeled as an inextensible Euler-Bernoulli beam is investigated for the primary resonance. The spring controller is designed to control the dynamic behavior of the nonlinear dynamic system. The method of multiple scales is utilized directly to obtain the linear equations. The effect of the feedback gain and time-delay on the steady state response is investigated. It is found that proper selection of the feedback gain and time-delay can enhance the control performance. The bifurcation can be eliminated or the position of bifurcation point can be changed.
