D. Vafiadis et N. Karcanias, MODEL-MATCHING UNDER EXTERNAL AND INPUT-OUTPUT EQUIVALENCE, Circuits, systems, and signal processing, 16(4), 1997, pp. 429-438
The model-matching problem for systems described by external models is
considered in frameworks of both external and input-output equivalenc
e. Necessary conditions for the solvability of the problem are produce
d, and it is shown that in certain cases these conditions are also suf
ficient. In the case where necessary and sufficient conditions exist,
the solutions of the problem are obtained in a constructive way and a
parametrization of solutions is given.
