Transformation of Hyperoutput Systems to a Form with Relative Degree

We consider the problem of transforming a hyperoutput linear control system to a form with relative degree using a nonsingular change of outputs. For square systems this problem is solved by introducing generalizations of relative degree. Likewise, the present paper extends various generalizations of relative degree to the case of hyperoutput systems and uses these generalizations to introduce a class of systems for which the stated problem can be solved.
