hydraulic cylinder synchronized controller using floodgate control and method thereof

摘要

The present invention relates to a hydraulic cylinder synchronization control device and method for hydrostatic fish to precisely synchronize the hydraulic cylinder for high-load hydrophobic fish irrespective of the nonlinearity of the hydraulic system and the load fluctuation according to the gate opening and closing conditions. In the present invention, a plurality of hydraulic cylinders for raising or lowering a high load hydrology are divided into a reference cylinder and a subordinate cylinder, and in the hydraulic cylinder synchronization control apparatus for a hydrophobic fish for synchronously controlling the reference cylinder and the subordinate cylinder, A plurality of displacement sensors for measuring the movement positions of the reference cylinder and the dependent cylinder in real time; A plurality of electromagnetic proportional flow control valves for controlling the flow rate supply of the reference cylinder and the dependent cylinder; Judging the moving direction of the floodgate according to the selection by the user, and controlling the flow rate supplied to the reference cylinder and the subordinate cylinder to correspond to the determined movement direction, when the synchronization error between the reference cylinder and the subordinate cylinder occurs A hydraulic cylinder tuning controller is provided to compensate for the tuning error. ; Hydraulic Cylinder, Hydraulic Cylinder Sync Control, Hydraulic Cylinder Sync Control
