The basic output feedback invariants for linear systems are discovered.         These invariants are a list of quantities from the knowledge of which           one can determine whether two systems are feedback equivalent.  There           are many important applications of these calculations; for example, it          is expected that they will lead to the solution of the problem of               determining a minimum order stabilizing compensator for a given plant.
