Abstract

An aspect of the present disclosure is a real-time weight compensation method for automatic swing control of a construction machine, wherein the construction machine comprises a lower traveling body and an upper structure swingably supported on the lower traveling body, the upper structure including an upper rotating body, a boom connected to the upper rotating body, an arm connected to the boom, and an attachment connected to the arm, the method comprising: measuring a current arm joint angle (θ<c>) using one or more detection means, measuring a current boom cylinder pressure (P<c>) at the current arm joint angle (θ<c>) using a pressure measuring means, calculating a pressure difference (ΔP) between the measured current boom cylinder pressure (P<c>) at the current arm joint angle (θ<c>) and a preset reference boom cylinder pressure (P<r>) at the corresponding arm joint angle (θ<c>), converting the calculated pressure difference (ΔP) into a preset reference additional weight (W<r>) at the corresponding pressure difference (ΔP), and updating a swing moment or inertia of the upper structure in real time by reflecting the reference additional weight (W<r>).
