CONTROL VALVE CONTROL SYSTEM

摘要

The control valve control system is intended to improve the responsibility of a control valve, that is, to reduce the time delay from a manipulation of the operation lever till the actuation of the valve. The delay is caused by the time necessary for calculation for control and by the inductance of the solenoid of the valve. The control system comprises means (2) for producing an electric signal (V0) that corresponds to the operation stroke of an operation lever (1), an advance compensation controller (7) having a differentiator (10) for differentiating the electric signal (V0) and an adder (12) for adding the value of the differentiation to the electric signal (V0), and a controller (4) for calculating an instruction value from the added value and for outputting a control signal (i2) to the control units (5, 6) of the control valve.
