Abstract

The application provides a pair of distributed electric cylinder reference compensation synchronization system and control method, and relates to the technical field of electromechanical servo control. The reference compensation synchronization system provided by the application aims to solve the problem of synchronization control in the high-speed movement process of multiple pairs of distributed electric cylinders, improve the situation that the load deformation and the imbalance of the electric cylinder torque are caused by the inconsistent extension and contraction of each electric cylinder, eliminate the hidden danger of mechanical damage caused by excessive deformation due to different structures, and provide a reference compensation synchronization control method. The selected electric cylinder extension and contraction is used as a reference, other electric cylinders make compensation algorithm according to the difference with the electric cylinder extension and contraction, and the position deviation left by the speed compensation in the high-speed movement of multiple electric cylinders is eliminated. In particular, since the pair of distributed electric cylinders have scalability, the carrying capacity and installation area of the load platform can be greatly improved accordingly.
