Abstract

In (Zhao and Bentsman, 2002} it has been shown that for most singlein put-single-output linear discrete-time systems in polynomial format, a sequential solution of a Diophantine equation and an algebraic equation is, in theory, sufficient to calculate the corresponding H2 and H controllers, Based on the results of (Zhao and Bentsman, 2002), the present work gives procedures for determining the sufficiency of a single Diophantine equation for controller calculation and for the actual calculation of the optimal controllers. Controller computations for nonminimum phase unstable plants have been carried out with relative ease.
