Abstract: A method for synchronous control of a gantry mechanism with online inertia matching is applicable to a machine tool equipped with a gantry mechanism. The gantry mechanism includes two rails, a crossbeam and a saddle, in which the saddle is disposed on the crossbeam, and the crossbeam is disposed by crossing the two rails. Each of the two rails is furnished with a driving apparatus for synchronously driving the crossbeam, and the driving apparatus includes a drive motor and a lead screw. This method includes the steps of: obtaining gantry-mechanism information; detecting position information of the saddle on the crossbeam; evaluating the position information and the gantry-mechanism information to derive load-inertia variety information; and, evaluating the load-inertia variety information to adjust torque-output information of the drive motor corresponding to the respective driving apparatus.
