Title:
MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/008222
Kind Code:
A1
Abstract:
A motor control device which achieves an improvement in control performance while ensuring the stability of a control system is provided. The drive of a motor (2) is controlled by a motor control device main unit (10). The motor control device main unit (10) comprises a pressure command signal generation unit (11), a pressure control unit (12), a speed control unit (13), a current control unit (14), and a parameter adjustment unit (100). With respect to a parameter for a control calculation by the pressure control unit (12), the parameter adjustment unit (100) comprises an information acquisition unit and a parameter calculation unit. The information acquisition unit acquires, from the outside, information relating to the elastic constant (K) of an object to be pressurized (7), a reaction force constant (h) indicating reaction force information, a transfer characteristic from motor torque to motor speed, and parameters (Kv, Kvi) for the speed control unit (13). The information acquisition unit previously acquires information relating to the control law of the speed control unit (13). The parameter calculation unit calculates a parameter for the pressure control unit (12) on the basis of the information acquired by the information acquisition unit.
