Abstract

A feedback control processing for computing a feedback control input value for controlling the posture of a construction machine using the control gain, in which a control parameter adjustment processing includes: overshoot computation processing for computing an amount of overshoot of a posture detection value with respect to a target position in a previous control section; addition/subtraction rate computation processing for computing a control gain addition/subtraction rate, which is an addition/subtraction rate of the control gain in the next control section, based on the amount of overshoot; addition/subtraction rate smoothing processing for computing a post-smoothing addition/subtraction rate in which the control gain addition/subtraction rate is smoothed based on a post-smoothing addition-subtraction rate computed in the previous control section and the control gain addition/subtraction rate; and control gain computation processing for computing the control gain in the next control section from the post-smoothing addition/subtraction rate.
