Based on new definitions of "control zeros" and minimum phase property for possibly nonsquare LTI MIMO discrete-time systems, generalizations of perfect regulation and perfect filtering are presented both for polynomial matrix and state space models. Consequently, general equivalence results are announced for multi-step and single-step optimal controls as well as for maximum-accuracy and maximum-speed controls for LTI MIMO discrete-time systems. The latter is made visible after the introduction of a new-category of time-optimal control, namely infimum-time control. The equivalence conditions refer to the system's right-invertibility and the (newly-defined) minimum phase behavior, which demonstrates the usefulness of the new approach to zeros of multi variable systems.
