CONTROL DEVICE OF CONSTRUCTION MACHINE AND CONSTRUCTION MACHINE EQUIPPED WITH THE SAME
To provide a control device of a construction machine capable of settling engine speed at an early stage, and a construction machine equipped with the control device.SOLUTION: An engine control device 100A is equipped with an engine speed sensor 101, and a control device 50. The control portion 50 executes feedforward control that computes load torque speed Trs that is time change of load torque Tr applied to an engine 10 on the basis of discharge amount Q instructed to a first hydraulic pump 11, and corrects a target rotation number according to at least the load torque speed, and a feedback control that corrects the target rotation number according to difference between the inputted target rotation number Nd of the engine rotation number Nr detected by the engine speed sensor 101.SELECTED DRAWING: Figure 3
【課題】早期にエンジンの回転数を静定させることが可能な建設機械の制御装置およびこれを備えた建設機械を提供する。【解決手段】エンジン制御装置１００Ａは、エンジン回転数センサ１０１と、制御部５０とを備える。制御部５０は、第１油圧ポンプ１１に対して指令される吐出量Ｑに基づいてエンジン１０にかかる負荷トルクＴｒの時間変化である負荷トルク速度Ｔｒｓを演算し、少なくとも負荷トルク速度に応じて目標回転数を補正するフィードフォワード制御と、入力されるエンジンの目標回転数Ｎｄとエンジン回転数センサ１０１によって検出された回転数Ｎｒとの偏差に応じて目標回転数を補正するフィードバック制御とをそれぞれ実行する。【選択図】図３
