Abstract: This brief proposes a simple criterion for selecting low order modes of discrete multivariable systems for model reduction. From the view point of power spectrum of the system output, the ...

Abstract: An indirect method for estimating the parameters of the reduced continuous-time model from the sampled input/output data is presented. In this method, a discrete-time ARMA model is first identified. ...

Abstract: A linear model following controller based on a reduced-order plant model is presented in this paper. The reduced model is composed of two submodels that characterize the dynamics during the ...
