A computer-implemented method for registering a controlled web (#30, Figs. 2A, 4A, 4B) to an on-line pitched unit operation (#50, Fig. 4A) with a machine cycle, the controlled web comprising a plurality of pre-produced objects (#22, Figs. 1, 2A, 2C, 4A, 4B) longitudinally spaced apart at a pitch interval (PP, Fig. 2B), wherein the method comprises: receiving one or more signals that represent a presence of each of the pre-produced objects; generating actual position bias data based, at least in part, on the signals, wherein the actual position bias data represent, for each of the pre-produced objects, an actual position of the pre-produced object relative to a machine cycle position of the pitched unit operation; generating a plurality of error signals that represent, for each of the pre-produced objects, a difference between a target position bias constant and the actual position bias data, wherein the target position bias constant represents a desired position of the pre-produced object relative to the machine cycle position of the pitched unit operation; generating an integral term, at least in part by summing the plurality of error signals; generating a correction signal, at least in part by summing the integral term and a proportional term; generating a gear ratio trim value by scaling the correction signal by a nominal gear ratio, wherein the nominal gear ratio is proportional to a translation of the controlled web over a corresponding translation of the pitched unit operation; and registering the controlled web to the pitched unit operation based, at least in part, on the gear ratio trim value, either characterized in that the generating of the integral term includes generating the integral term that is proportional to the inverse of a target time constant expressed in pre-produced objects, and wherein the generating of the integral term includes generating the integral term that is proportional to: 1 4 τ p ζ 2 wherein τ P is a target time constant expressed in pre-produced objects; and wherein ζ is a damping factor, or characterized in that generating the proportional term that is proportional to: 1 τ P wherein τ P is a target time constant expressed in pre-produced objects. receiving one or more signals that represent a presence of each of the pre-produced objects; generating actual position bias data based, at least in part, on the signals, wherein the actual position bias data represent, for each of the pre-produced objects, an actual position of the pre-produced object relative to a machine cycle position of the pitched unit operation; generating a plurality of error signals that represent, for each of the pre-produced objects, a difference between a target position bias constant and the actual position bias data, wherein the target position bias constant represents a desired position of the pre-produced object relative to the machine cycle position of the pitched unit operation; generating an integral term, at least in part by summing the plurality of error signals; generating a correction signal, at least in part by summing the integral term and a proportional term; generating a gear ratio trim value by scaling the correction signal by a nominal gear ratio, wherein the nominal gear ratio is proportional to a translation of the controlled web over a corresponding translation of the pitched unit operation; and registering the controlled web to the pitched unit operation based, at least in part, on the gear ratio trim value, either characterized in that the generating of the integral term includes generating the integral term that is proportional to the inverse of a target time constant expressed in pre-produced objects, and wherein the generating of the integral term includes generating the integral term that is proportional to: 1 4 τ p ζ 2 wherein τ P is a target time constant expressed in pre-produced objects; and wherein ζ is a damping factor, or characterized in that generating the proportional term that is proportional to: 1 τ P wherein τ P is a target time constant expressed in pre-produced objects.
