Abstract (en)
The present invention relates to a control apparatus for a construction machine such as a hydraulic excavator for excavating the ground, and includes angle detection means (20 to 22) for detecting a posture of a joint type arm mechanism in angle information, conversion means (26) for converting the detected angle information into corresponding expansion/contraction displacement information of cylinder type actuators (120 to 122), and controlling means (1) for controlling the actuators (120 to 122) based on the obtained expansion/contraction information so that the actuators (120 to 122) may perform predetermined expansion/contraction displacements, whereby the position and the posture of a working member (400) can be controlled accurately and stably while suppressing the cost low. <IMAGE>
