The performance of robust controllers depends on the set of candidate plants, but at present this intimate connection is untransparent. The aim of this paper is to construct a model set to improve the performance in a subsequent robust control design. Analysis of uncertainty structures reveals that there is an unexploited freedom in the realization of coprime factorizations in the dual-Youla uncertainty structure. The main result of this paper is a specific coprime factorization that results in… CONTINUE READING
