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 algorit hm is proposed to minimize pole placement error so as to achieve the desire d closed-loop performances better. It is shown that the proposed design alg orithm not only has a fast rate convergence in the search of maximum tolera nce with regard to pole placement error but also is easy to understand and convenient to implement. A numerical example is given to illustrate the app lication of the design algorithm.
