Abstract
Operation of a carriage is controlled to actuate a mechanism. The carriage is controlled according to a feed forward term and a feedback term, to compensate interaction of the carriage with the mechanism. Thus, the carriage is to engage the mechanism at a reduced velocity for quiet operation, and fully and reliably actuate the mechanism without stalling the carriage.
