Title:
ACTUATOR CONTROL DEVICE AND WORKING MACHINE EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2011/114765
Kind Code:
A1
Abstract:
Provided is an actuator control device capable of suppressing vibration during a regeneration period. The actuator control device comprises: a target speed calculation means (121) for calculating a target number of rotations of a motor; a load detection means (2) for detecting a load imposed on an actuator; a torque command calculation means (123) for calculating a torque command of the motor on the basis of the load; a current command calculation means (131) for calculating, from the torque command, a current vector command to be flowed to the motor; a current detection means (5a); a current conversion means (132) for converting current to a current vector; a voltage command calculation means (133) for calculating a voltage vector command according to the deviation between the current vector command and the current vector; and a voltage conversion means (134) for converting the voltage vector command to a voltage command and outputting the voltage command to a control unit of the motor. The current conversion means and the voltage conversion means perform the respective conversions on the basis of the target number of rotations calculated by the target speed calculation means.
