# Control device of construction machine

## Abstract

A control apparatus of a construction machine, such as hydraulic excavator, includes arms supported on the construction machine body side, a working member supported by the arms and hydraulic cylinder actuators for operating the arms and the working member, for realizing a smooth variation of an instruction value to the hydraulic cylinder actuators even if the working member is operated suddenly upon starting an operation. In the control apparatus, the arm and working members are operated by driving a control member, a target moving velocity of the working member is set so that the characteristics of the arms and working member upon starting an operation and upon ending an operation as time differentiated are regarded as those before time differentiated, and the actuators are controlled based on the target moving velocity information so that the working member is operated at the target moving velocity.
