Abstract
In the model matching problem, proper plant Pand
model T are given and a proper M is to be found such
that T = PM. M can then be realized via feedback and
feedforward compensation. For internal stabilityT
and M must be stable. A proper and stable solution
M exists only when the unstable finite and infinite
zeros of P also appearin T. This is studied using
the interactor and the Hermite forms ofP and T, di
rectly using factorizations of the transfer matrices
and by utilizing and extending resultsof the related
nominal synthesisproblem. How to choose an appropri
ate T in control design is also discussed using poly
