Adaptive sliding mode strategy: a cross-coupled synchronization control method for improving the dynamic accuracy of dual-drive gantry systems under spatial perturbations
Dual-drive feed systems are widely applied in high-end manufacturing. However, their synchronization accuracy is severely limited by nonlinearities, including weak mechanical coupling, nonlinear friction, and time-varying inertia induced by center-of-gravity (CoG) shifts. To address these issues, this paper proposes a...
