We address the disturbance decoupling problem of periodic and multirate discrete time systems via synchronous controllers. A theory of multifeedback controlled invariant subspaces is developed. Based on this theory, a constructive solution for the solvability of the disturbance decoupling problem is presented. A complete characterization of the friend set of a given multifeedback controlled invariant subspace and a partial characterization of the DDP PTD solutions are offered.
