    摘要: A method for controlling operation of a hydraulic valve having a magnet fixed to a displaceable spool, a sensor producing a signal responsive to the sensed intensity of a field produced by the magnet representing the position of the spool in the valve spool, the method comprising producing from the signal a time series record of the position of the spool; determining the desired position of the spool, producing a error signal from the difference between actual and desired spool position, determining a compensated correction error, producing a commanded control pressure signal to change the magnitude of control pressure supplied to the valve, and changing the position of the spool in response to the control pressure signal.
