Pade extended prony (PEP) model reduction for linear multivariable systems

In this paper we develop a general idea of Pade.ex tended Prony (PEP) modelling which reduces to the classical Pade and.(extended) Prony models as special cases. The formulation includes development of PEP models based on min /spl par/ /spl dot/ /spl par//sub 2/ norm ( in the classical sense) and a new min /spl par/ /spl dot/ /spl par//sub 1/ norm (in the robust sense).
