Summary:For the discrete-time, normalized left-coprime factorization
robust stabilization problem, it is known that a simple formula for the
maximum robustness margin exists. Moreover, the controller can be
written in exact observer form. Analogous results are derived when the
controller is restricted to be strictly proper
