Abstract:
A new position control apparatus is provided which can reduce deviation caused by a non-linear spring characteristic of a rolling apparatus. In a position control apparatus ( 5 ) that controls the position of a movable body ( 1 ), in a positioning apparatus ( 9 ) including a rolling apparatus ( 2 ), a deviation e(t) or d of the movable body  1  caused by the non-linear spring characteristic of the rolling apparatus ( 2 ) is subtracted from or added to a position command Xref or r of the movable body ( 1 ). The deviation d is calculated by carrying out equivalent exchange on a control circuit for a friction force of the rolling apparatus ( 2 ), which is set as a quantity of the dimension of displacement.

Claim (Index 9):
The position control apparatus according to  claim 4 , wherein\n the rolling apparatus includes a ball screw that drives the movable body, the position control apparatus uses a PI controller for speed control, and the deviation d is calculated from the following equation (16); d = \u03c4 \u00b7 1 Kp \u00b7 L 2 \ue89e \u03c0 \u00b7 s Kv \u00b7 s + Ki \u00b7 1 J ( 16 ) where \u03c4 is the friction torque of the ball screw, Kp is the position loop proportional gain, L is the lead of the ball screw, Kv is the angular velocity proportional gain, Ki is the angular velocity integral gain, J is the load inertia, and s is the Laplace operator.
