Apparatus for controlling hydraulic pump for construction machine
The present invention relates to an apparatus for controlling a hydraulic pump for a construction machine. The apparatus for controlling a hydraulic pump for a construction machine according to the present invention comprises: a hydraulic pump control device (100) for generating first and second pump commands (Pcmd1, Pcmd2) and controlling first and second hydraulic pumps (P1, P2), so as to implement pump torque corresponding to a request value; and a torque control unit (200) for generating first and second corrected pump commands (Pcmd11, Pcmd22) by correcting the first and second pump commands (Pcmd1, Pcmd2), respectively, on the basis of a torque inclination map (220), which has been generated by the hydraulic pump control device (100) by reflecting engine dynamic characteristics, and for providing the first and second hydraulic pumps (P1, P2) with the first and second corrected pump commands (Pcmd11, Pcmd22).
