Abstract:
In this thesis, performance bounds for the optimal control of discrete-time LTI plants are proposed. Results of stable plants with relative degree but no finite nonminimum-phase zero that have been done in the literature, are reported. According to model-matching problem and Nehari’s Theorem for finding performance bound in discrete-time, an algorithm in seven steps is posed. Meanwhile by using of presented algorithm, a case of nonminimum phase stable plants and several cases of unstable plants for finding performance bound is studied. By using of Matlab, A program for performance bound in plants with no poles Nor zeros on the unit circle is presented.
