A New Condition for Accurately Aggregated Model Reduction

摘要：

A new condition for accurately aggregated model order-reduction of large-scale systems is presented,which can be used to determine whether the accurate order-reduction model exists for a given order or certain variable components previously assigned. The corresponding reduced-order model is also derived under the proposed existence condition.It is shown that,if the condition is not satisfied,an approximate model order-reduction can be carried out.Simulation results are shown to verify the validity and feasibility of this method.
