摘要：AbstractIn this paper, a new model reduction technique based on the generalized limited frequency interval cross Gramian is developed for continuous linear time invariant systems. The proposed technique is not only applicable to unstable systems but can also be applied to the systems which contain eigenvalues of opposite polarities and equal magnitude. The standard cross Gramian is generalized for such systems by transforming the system matrix of the original system using a Riccati equation.
