一种高效的频域模态参数识别法

EFFICIENT METHOD FOR IDENTIFICATION OF MODAL PARAMETERS IN FREQUENCY DOMAIN

提出了一种高效提取模态参数的识别方法。在单输入单输出 (SISO)或单输入多输出 (SIMO)系统中 ,不论模态参数密集的程度 ,该方法都可以有效提高模态参数识别的精度与速度。最后 ,通过实例验证对比 。

An efficient method for identification of modal parameters is provided. No matter how dense the modal parameters are, this method can improve validly the precision and the speed of identifying modal parameters in the systems of SIMO (Single Input and Multiple Output) or SISO (Single Input and Single Output). Two examples are provided to validate the efficiency of the method.
