Metal band sawing machine GB4230 hydraulic clamping steel bar sawing

The servo position control module of the GB4230 hydraulic clamping steel bar sawing machine adopts a combination of sampling interpolation and predictive control for position control (specific control is omitted). Shanghai Guangnai Electromechanical determines the position to close the feeding cylinder based on system experience values and current status, so that the feeding cylinder reaches the target position just when it stops. Due to electromagnetic mechanical hysteresis and motion inertia, it is almost impossible to control the feeding slide to move 0.1mm through "on" and "off".
