Abstract
A control system for a construction machine maintains operability of a swing combined operation even when the power supplied from an engine or storage device varies. The control system includes a target path computation section that receives an operation amount of the front implement operation device, an operation amount of the swing operation device, a speed of the front implement drive unit detected, and an angular speed of the swing structure drive unit, 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 the target path the front implement operation device and the swing operation device are operated simultaneously.
