Abstract
Let G(z1, z2) be ap x m 2D proper rational transfer matrix, with full column rank, and SIGMA = (A1, A2, B1, B2, C, D) a state-space realizat ion of its. Necessary and sufficient conditions are presented in this paper, which guarantee that (i) G(z1, z2) admits polynomial left inver ses, (ii) such polynomial inverses are transfer matrices of some inver se system of SIGMA. When the above conditions are not fulfilled. the e xistence of stable and/or proper possibly delayed, inverses of G(z1, z 2), is also discussed.
