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 reflection vector polytope and robust controller design by quadratic programming approach. The roots placement of reflection vectors is studied and the weights for reflection vectors are calculated.
