Robust design of pole placement controllers in the presence of structured uncertainty

This paper addresses the robust design of pole placement controllers in the presence of structured parametric uncertainty in a plant. A design algorithm is proposed to minimize pole placement error so as to achieve the desired closed-loop performances better. It is shown that the proposed design algorithm not only has a fast rate convergence in the search of maximum tolerance with regard to pole placement error but also is easy to understand and convenient to implement. A numerical example is given to illustrate the application of the design algorithm.
