Abstract :
A constructive procedure for robust output controller design is given starting from the unit hypercube of reflection coefficients of monic polynomials. This procedure consists of two main steps: convex approximation of the stability domain by a polytope and robust controller design by quadratic programming approach. A generalization for all stable polytopes is given by the use of a Schur invariant transformation with a free parameter.
