DRIVE CONTROLLER FOR CONTROL OBJECT, ITS DRIVE CONTROLLING METHOD, IMAGE RECORDER AND ITS CONTROLLING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a controller for a control object and an image recorder mounted with the controller in which the control object can be controlled stably without damaging the performance for following up a control command value when the control object is accelerated from stop state up to a specified speed. SOLUTION: A drive start power value required for starting a control object to drive from stop state is detected while gradually applying a specified power at a time. A command speed and a command position for driving the control object are set for each specified drive timing and a drive power value after driving is calculated based on the difference from actually measured position and speed of the control object. When the control object is driven through the controller, it is driven at first using the drive start power value and then controlled using the drive power value after starting driving. Stabilized control can thereby be ensured without damaging the performance for following up the control command value.
