Abstract
The velocity and force of a target is controlled to have a predetermined relationship, independently of changes in the velocity at which the target is driven using a velocity command value and in an external force from the target. A controller controls a control target, driven to generate a predetermined viscous force as a reaction force, by periodically outputting a command value to the control target using a target value calculated from a command pattern for driving the control target and a feedback value from the control target relative to the target value. A correction operation unit obtains a control physical quantity different from the command value, calculates a correction command value based on a relationship between an error of the obtained control physical quantity from its target value and an error of the feedback value from the target value, and outputs the correction command value to the control target.
