Suboptimal model reduction by multi‐point Padé approximation
A novel Pade approximation method is used to obtain a reduced-order transfer function, with a predetermined denominator, such that the integral square error between the time responses ofthe full and reduced models is minimized. The method is seen to be easy to apply compared with existing suboptimal order reduction methods. A numerical example is given to illustrate its application.
