Abstract:
1. A control apparatus for a work machine comprising: a hydraulic pump which is driven by an engine; a hydraulic actuator to which pressurized oil is supplied, the pressurized oil being discharged from the hydraulic pump; a generator motor which is coupled to an output shaft of the engine; a storage device which accumulates electric power generated by the generator motor and supplies electric power to the generator motor; an electric actuator which is driven by the electric power generated by the generator motor and/or the electric power accumulated in the storage device; a determination unit which determines whether or not the hydraulic actuator and the electric actuator are concurrently actuated; and a control unit for restricting a torque or a speed of the electric actuator when the determination unit determines that the hydraulic actuator and the electric actuator are concurrently actuated.
