ABSTRACT:
Periodic gain adjustment in plants of irreducible order, n, or for equalization of communications channels is effected in such a way that the plant (system) appears to be minimum phase by choosing a horizon time N>n of liftings in periodic input and output windows .rho..sub.u and .rho..sub.y, respectively, where N is an integer chosen to define the extent (length) of each of the windows .rho..sub.u and .rho..sub.y, and n is the order of an irreducible input/output plant. The plant may be an electrical, mechanical or chemical system, in which case output tracking (OT) is carried out for feedback control or a communication channel, in which case input tracking (IT) is carried out. Conditions for OT are distinct from IT in terms of zero annihilation, namely H.sub.s H.sup.+.sub.s =I for OT and H.sub.s.sup.+ H.sub.s =I of IT, where the OT conditions are intended for gain adjustments in the control system, and IT conditions are intended for equalization for communication channels.
