Balanced realization of Pade approximants of e/sup -sT/
James Lam · IEEE Transactions on Automatic Control · 1991
An algorithm to calculate the balanced realization of all-pass Pade approximants of e/sup -sT/ is presented. The algorithm makes use of a regular C-type continued fraction expansion of e/sup -sT/ and a properly scaled recurrence formula is used to generate the coefficients of the Pade denominator polynomial. A truncation property of the balanced realization is discussed.>
