AI Technical Summary

Technical Problem

During the bending process of metal sheets, the synchronization of multi-axis drive systems is difficult to guarantee, which can lead to deformation or damage of the sheets, affecting production efficiency and product quality. Existing technologies cannot effectively identify and decouple the coupling effect between axes, resulting in insufficient robustness and control precision.

Method used

A dynamic reconstruction virtual axis system based on coupling situation recognition is adopted. Through a decoupling control method with parallel operation of dual loops, beneficial coupling is actively used to enhance coordination, suppress harmful coupling, and improve synchronization accuracy and robustness.

Benefits of technology

It enables in-depth perception and qualitative differentiation of inter-axis interactions, improves the synchronization accuracy, robustness, and adaptability of the control system, and reduces the difficulty of adapting to changes in operating conditions.
