Abstract :
A novel mixed randomized/deterministic method to robust fixed-order controller design is proposed for discrete-time SISO plants. It is based on the random generation of Schur stable polynomials using reflection coefficients and reflection polytopes of polynomials. Stable reflection segments are projected onto affine set of closed-loop characteristic polynomials and the stabilizing polytopes in the controller parameter space are determined.
