ABSTRACT:
An imaging system for processing a media includes a media transport path, an imaging station, a displacement device that controllably displaces the media along the media transport path relative to the imaging station, and a controller assembly. The controller assembly includes a feedback filter, a feedforward filter, a low-pass filter and a memory that stores and time delayed releases control data. During operation, the displacement device is actuated in response to an actuation command generated by the controller assembly. The actuation command has a feedback component based on a filtering by the feedback filter of an error signal including information about the position error between a desired and an actual position of the media and a feedforward component based on a time delayed, low-pass filtered, frequency dependent filtering of the error signal by the feedforward filter. The feedforward filter is configured such that the closed-loop controlled characteristics of the displacement device are compensated.
