<p><P>PROBLEM TO BE SOLVED: To adequately carry out switching control between positional control of a contact member such as a die cushion and force control regardless of ability of a worker and in spite of input delay of a sensor. <P>SOLUTION: Positional relation between an object to be contacted and the contact member such as the die cushion is estimated using the mathematical model of the object to be contacted such as a slide and a mathematical model of an actuator. The actuator is controlled based on the positional relation so that the control of the switching timing between the positional control of the contact member and the force control is carried out. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
