<p>A machine tool moves a driven member by use of a servomotor. A position control device controls the position of the driven member in accordance with full closed loop control. The position control device computes an integrated feedback value g in correspondence with a function F (V M , P M , V m , P m ) in which four state amounts, motor speed V M , motor position P M , driven member speed V m , and driven member position P m are independent variables. The thrust instruction Ä*, which is inputted to the servomotor, is compensated with the integrated feedback value g. The servomotor is thus optimally driven and controlled in accordance with full closed loop control.</p> |
