Abstract
A controller for a work implement (10, 30) of a construction machine (1, 3) comprising: a manipulating signal input unit (21) including a target value computing section (25) for generating an operation target value (V1) for the work implement (10, 30) based on a manipulating signal (F, Fa) inputted from a manipulating unit (2) for manipulating the work implement (10, 30), a target value correcting unit (22, 37) for correcting the generated operation target value (V1), and an instruction signal output unit (23) for outputting an instruction signal to an actuator (19, 34) for driving the work implement (10, 30) according to the corrected target value (V2); wherein the target value correcting unit (22, 37) comprises a vibration suppressing unit (29) for correcting the operation target value (V1) to another target value to suppress vibrations of the construction machine (1, 3) according to the vibration characteristics, which vary according to a posture of and/or a load to the work implement (10, 30).
