Title:
DRIVE CONTROL DEVICE FOR ROTATING WORK MACHINE AND ROTATING WORK MACHINE PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2023/219015
Kind Code:
A1
Abstract:
A drive control device (101) of a rotating work machine (100) comprises: a compensation control valve (33) which is interposed between a hydraulic pump (22) and a first actuator (7), and for which the degree of opening can be adjusted so as to change the flow rate of hydraulic oil supplied from the hydraulic pump (22) to the first actuator (7); a rotational operation device (42) to which a rotational operation for operating a rotational motor (11) is applied; a first operation device (41) to which a first operation for operating the first actuator (7) is applied; and a controller (70) that adjusts the degree of opening of the compensation control valve (33) such that the actual rotational acceleration is adjusted to a target rotational acceleration based on the operation amount of the rotational operation during a composite operation of the first operation and the rotational operation.
