摘要： A control system for a construction machine that can stop an upper swing structure at a desired swing stop angle is provided. A main controller includes: a swing stop target angle setting section that sets a swing stop target angle that is a target angle at which an upper swing structure is stopped; a swing control section that outputs a drive command to a control valve in such a manner that a speed reduction of swing of the upper swing structure is executed; a swing stoppability determination section that reads an angle signal of the upper swing structure with respect to an undercarriage detected by a first angle sensor and an angle signal of a work implement detected by a second angle sensor, and that determines whether the swing of the upper swing structure can be stopped at the swing stop target angle on the basis of these signals; and a work implement control section that outputs drive command signals to control valves in such a manner an extension action of the work implement in a swing radial direction is prohibited or a contraction action of the work implement in the swing radial direction is executed in response to a signal that indicates whether the swing can be stopped and that is determined by the swing stoppability determination section.

摘要： In drive control of an operating machine configured to drive a structure by a hydraulic motor (2) configured to be driven by operating oil supplied from a hydraulic pump (10) and an electric motor (3) configured to cooperate with the hydraulic motor (2), a speed command generated based on a manipulation amount of a remote control valve (5) configured to determine an operation amount of the structure is subjected to speed feedback control performed based on the actual rotation speed of the hydraulic motor (2) and pressure difference feedback control performed based on an operating oil pressure difference between a suction port and discharge port of the hydraulic motor (2). With this, a tilting angle command is generated such that the operating oil, the amount of which is necessary at the actual rotation speed of the hydraulic motor 2, is ejected, and the tilting angle of the hydraulic pump (10) is controlled. Thus, the amount of oil supplied from the hydraulic pump to the hydraulic motor is controlled in accordance with the manipulation amount of the remote control valve, the rotation speed of the hydraulic motor, and the operating oil pressure difference between the suction port and discharge port of the hydraulic motor. As a result, energy loss is suppressed.

摘要： There is provided a slewing control device (13) that enables to detect breakdown of a driving system of a mechanical brake (4), and generate a torque for holding a slewing body in a stopped state to thereby prevent movement of the slewing body when an anomaly has occurred. In a working machine for driving a slewing body by an electric motor (1), judgment is made as to whether a mechanical brake (4) is in an inconsistent state, based on a command to be outputted to a brake circuit (B), and a pressure detected by a brake pressure sensor (17). The inconsistent state is a state that the mechanical brake (4) is in a brake released state when an activation command for switching the mechanical brake (4) to a brake activated state is outputted. If it is judged that the mechanical brake (4) is in the inconsistent state, a command for obtaining a braking torque for holding the slewing body in a stopped state is outputted to the electric motor (1).
