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 5):
The position control apparatus according to  claim 4 , wherein\n the rolling apparatus includes a rolling guide apparatus that guides the movable body, the positioning apparatus includes a linear motor 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 (11);\n d=Ti\u00b7v ( t )\u00b7 d \u03b4( x \u2032)/ dx\u2032 \u2003\u2003(11) \n where \u03b4\u00b7(x\u2032)=f(x\u2032)/(Kp\u00b7Kv\u00b7M), x\u2032 is the position of the movable body having an origin at a point where the velocity is reversed, f(x\u2032) is the friction force of the rolling guide apparatus expressed in a function of x\u2032, Ti is the integral time, v(t) is the velocity of the movable body, Kp is the position loop proportional gain, Kv is the velocity loop proportional gain, Ti is the integral time, and M is the mass of the movable body.
