CONTROL DEVICE FOR CONSTRUCTION MACHINERY

摘要

A control system for a construction machine, capable of maintaining excellent operability for a swing-combined operation even if power suppliable from an engine or electric power suppliable from a storage device varies is provided. The control system includes: a front implement speed detector that detects a speed of a front implement drive unit; a swing structure speed detector that detects an angular speed of a swing structure drive unit; a target path computation section that receives an operation amount of the front implement operation device, an operation amount of the swing operation device, the speed of the front implement drive unit detected by the front implement speed detector, and the angular speed of the swing structure drive unit detected by the swing structure speed detector, and that computes a target path of a claw tip position of the front implement drive unit; and an actuator power computation section that regulates power supplied to the front implement drive unit or the swing structure drive unit in such a manner that a claw tip of the front implement drive unit follows up the target path computed by the target path computation section when the front implement operation device and the swing operation device are operated simultaneously.
