摘要：

The basic formula of a parametric maximum likelihood estimator (MLE) in the frequency domain for multi-input, multi-output (MIMO) systems is given. The proposed method takes into account the perturbation noise on all the measured input and output signals. It is an extension to MIMO systems of the single-input, single-output (SISO) estimation method called ELiS (Estimation of Linear Systems). The MIMO estimator will be shown to determine more accurately the natural frequencies and damping ratios of mechanical structures than the SISO estimator. The estimators are applied to very noisy flight flutter data. © 1990.
