[CN 202110181519.4] Control system and method for flexible docking of hydraulic press movable beam and leveling system
[CN 202110181519.4] Title of control system and method for flexible docking of hydraulic machine movable beam and leveling system: control system and method for flexible docking of hydraulic machine movable beam and leveling system application number: CN 202110181519.4 applicant: Fuzhou university application date: 2021-2-7 patent type: invention application the present invention relates to a control system and method for flexible docking of hydraulic machine movable beam and leveling system. Input command signals with the same difference to the proportional servo valve of the leveling cylinder to control the leveling cylinder to fall circularly and collect the leveling cylinder displacement and rod-less cavity pressure, and record the corresponding command signals; use neural network algorithm to model the collected data, obtain the valve port flow model of the leveling cylinder control valve, and calculate the feed-forward value of the speed valve port of each leveling cylinder; then, collect the position information of the movable beam and the four leveling cylinders in real time, according to the displacement difference, the valve port opening of each leveling cylinder control valve is calculated, and the displacement deviation compensation module of the four leveling cylinders adjusts and compensates the valve port of each cylinder control valve. The invention adopts the coordinated control of the master cylinder and the leveling system and the four-cylinder coordinated control method, can realize the flexible docking of the movable beam and the hydraulic leveling system, and has strong engineering adaptability.
