Item This letter presents a one-shot algorithm, for inverting both Cauer I and II forms of continued fraction. The algorithm, which is amenable to digital computation, proceeds in the forward direction yielding at every stage the corresponding transfer function.

All rights reserved.(Cauer continued fraction methods for model reduction) Parthasarathy, R.; John, S.1981Item A new generalized algorithm, which can be programmed on a digital computer, is established for performing the inversion of the Cauer type continued fractions. © 1980 IEEE(A Generalized Algorithm for the Inversion of Cauer Type Continued Fractions) Parthasarathy, R.; John, S.1980Item This letter presents a procedure for obtaining reducedader models in statespace formulation, using modifd Cauer continued fraction as the basis. The proposed procedure is amenable to programming on a digital computer. Copyright © 1982 by The institute of Electrical and Electronic Engineeer, Inc.(State-Space Models Using Modified Cauer Continued Fraction) Parthasarathy, R.; John, S.1982Item A simple algorithm for obtaining the continued fraction quotients in the modified Cauer form (MCF) from the given system matrices in companion form is presented. In the sequel, the triple of all lower order models in companion form is directly obtained. A matrix method of obtaining the time-moments and Markov parameters from the MCF quotients is also outlined. Finally, it is shown that system reduction by matching a set of MCF quotients is equivalent to system reduction by matching a set of time-moments and Markov parameters.
