Patent ID: 8068262

Claim:
An imaging system for processing a media, comprising: a media transport path; an imaging station arranged along said media transport path; a displacement device that controllably displaces the media along said media transport path relative to said imaging station; and a controller assembly, the controller assembly comprising: a feedback filter; a feedforward filter; a low-pass filter; and a memory that stores and time delayed releases control data, wherein during operation, the displacement device is actuated in response to an actuation command generated by the controller assembly, the actuation command having: a feedback component based on a filtering by the feedback filter of an error signal comprising information about the position error between a desired position and the 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 being configured such that the closed-loop controlled characteristics of the displacement device are compensated.
