摘要本文研究了谐波激励光束的动态吸收问题。结果表明，通过在单点处施加反馈控制，可以使振动在期望位置处的谐波响应消失。给出了控制增益的两个表达式。一种是基于形变，另一种是基于光谱数据。分析了被控系统的稳定性。数值算例验证了各种结果。
Abstract The paper deals with dynamic absorption in a harmonically excited beam. It is shown that the harmonic response of vibration at a desired position can be made to vanish by applying a feedback control at a single point. Two expressions for the control gain are given. One is based on deformation and the other is based on spectral data. The stability of the controlled system is analysed. Numerical examples demonstrate the various results.
