| description | A drive control apparatus (101) for a slewing-type working machine (100) includes: a compensation control valve (33) between a hydraulic pump (22) and a first actuator (7) that has an adjustable opening degree for changing a flow rate of hydraulic oil to be supplied from the hydraulic pump (22) to the first actuator (7); a slewing manipulation device (42) that receives a slewing manipulation for actuating a slewing motor (11); a first manipulation device (41) that receives a first manipulation for actuating the first actuator (7); and a controller (70) that adjusts, during a combined manipulation of the first manipulation and the slewing manipulation, the opening degree of the compensation control valve (33) to cause an actual slewing acceleration to reach a target slewing acceleration according to a manipulation amount of the slewing manipulation. |
