Abstract

This paper presents multipoint Pade approximation for discrete interval systems. The numerator and denominator of the reduced model are obtained such that G/sub m/(z) to be a Pade approximant of G/sub s/(z), about 2r points. The expansion points used in the approximation could be a mixture of real, imaginary, complex and multiple points, many of the computational difficulties for such a combination of points are eliminated by this method. Numerical examples illustrate the procedure.
