The construction of an interactor canceling the infinite zeros of a non-square proper transfer matrix is discussed in this paper. Some new properties of the infinite eigenstructure of the system matrix pencil of the transfer function are presented by investigating the numerically stable algorithm in Dooren (1979). Then, a direct and numerically stable state-space design of the interactor is proposed. Unlike Copeland and Safonov (1992), this paper does not use the relation between the infinite zero structure of the transfer function in the frequency domain and the infinite eigenstructure of the system matrix pencil of the transfer function for the derivation of the interactor.
