ABSTRACT:
A position control apparatus and method has been devised which provides for an improved means of suppressing tracking error from a variable position reference occurring when a control object positioned via a transmission mechanism with mechanical transmission error resumes movement from a state stopped at a target position. A selection between two alternative tracking error compensating means within the control apparatus is made based on whether the detected position of the control object changes in a period after the control object stops and before the variable position reference is input again to a control deviation generating unit.
