1.引官 模态参数识别方法在应用中需要解决的一个重要问题是观测噪声的干扰问题。为了有效地抑制观测噪声的影响,各种时域参数识别方法普遍引入了估计方法,以ITDM为代表的利用脉冲响应包括对脉冲激励的响应和脉冲响应函数)识别模态参数的识别方法还引入了噪声模态
1. Introduction to the modal parameter identification method in the application of an important problem to be solved is the observation of noise interference. In order to effectively suppress the influence of observation noise, various time domain parameter identification methods generally introduce the estimation method, and the use of impulse response represented by ITDM includes the impulse response and impulse response function. The method of recognizing modal parameters is also introduced The noise mode
