Control device for construction machine, and construction machine provided with same
A control device (100A) is provided with a rotational speed detection unit (101) and a control unit (50). The control unit (50) executes each of a feed-forward control for calculating a load torque speed (Trs) applied to the engine (10) on the basis of a discharge amount (Q) commanded to the hydraulic pump (11) and for correcting the target rotational speed in accordance with at least the load torque speed, and a feedback control for correcting the target rotational speed (Nd) of the engine on the basis of the deviation between the target rotational speed (Nd) of the engine and the rotational speed (Nr) detected by the rotational speed detection unit (101) in accordance with the deviation between the target rotational speed (Nd) of the engine and the rotational speed (Nr) detected by the rotational speed detection unit (101). And correcting the target rotating speed.
控制装置(100A)包括转速检测部(101)和控制部(50)。控制部(50)分别执行前馈控制和反馈控制,所述前馈控制基于对液压泵(11)指令的喷出量(Q),运算施加至发动机(10)的负荷转矩速度(Trs),并至少根据负荷转矩速度来修正目标转速,所述反馈控制根据发动机的目标转速(Nd)与由转速检测部(101)检测出的转速(Nr)的偏差,修正目标转速。
