An Algorithm For Interval Continuous –Time MIMO Systems Reduction Using Least Squares Method

摘要

A new algorithm for the reduction of Large Scale Linear MIMO (Multi Input Multi Output) Interval systems is proposed in this paper. The proposed method combines the Least squares methods shifting about a point 'a' together with the Moment matching technique. The denominator of the reduced interval model is found by Least squares methods shifting about a point 'a' while the numerator of the reduced interval model is obtained by Moment matching Technique. The reduced order interval MIMO models retain the steady-state value and stability of the original interval MIMO system. The algorithm is illustrated by a numerical example
