<p>The present invention relates to a system for controlling a valve for a hydraulic cylinder. The objective of the present invention is to perform fine valve control by calculating an interrupt number in one cycle of a PWM signal to match the synchronization of the total output, simultaneously applying the calculated interrupt number to driven valves to synchronize the valves, and adjusting the position of a pulse in the cycle through the control of the amount of current supplied to the valve without changing a position in one cycle of a driving frequency of the valve. To achieve the objective of the present invention, the system for controlling a valve for a hydraulic cylinder comprises: an input unit to receive a value for driving a valve for a hydraulic cylinder; a synchronization unit to synchronize driven valves by calculating an interrupt number in one cycle of a PWM signal and simultaneously applying the calculated interrupt number to the driven valves to match the synchronization of the total output while transmitting the value inputted through the input unit to the valve; and a valve control unit to perform fine valve control by adjusting the position of a pulse in the cycle through the control of the amount of current supplied to the valve without changing a position in one cycle of a driving frequency of the valve.</p> |
