Title:
GANTRY MACHINE TOOL MOVING BEAM CROSS COUPLING CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2024/037394
Kind Code:
A1
Abstract:
The present invention relates to the field of control of numerical control machine tools. Disclosed is a gantry machine tool moving beam cross coupling control method. The gantry machine tool moving beam cross coupling control method comprises: step 1: establishing a cross beam dynamics model taking into consideration a ram on a cross beam, and simplifying the model for the design of an observer; and step 2: according to a parameter setting method for a single-side servo control system, PID control parameter setting of motors at two ends is achieved, and the servo systems having a same control parameter are used to jointly drive the cross beam to move up and down, so as to achieve synchronous control. Compared with the prior art, the beneficial effects of the present invention are that: during actual application to a large moving beam-type gantry processing center, the present invention reduces synchronization errors caused by torsion of the cross beam due to a mechanical structure difference, resolves synchronization errors caused by asymmetry of loads on two sides of a cross beam moving part in the moving process, and improves the robustness and stability of the system.
