Abstract: With the use of centre manifold and dynamic system theory, the necessary and sufficient conditions are obtained for the solvabilities of the output regulator problems for the general nonlinear discrete-time system.This work generalizes and refines the corresponding results ac Isidori and Byrnes on the affine nonlinear continuous-time system.

Key words: discrete-time system, output regulation, centre manifold, exponentialstability, ω-limit set
