Title:
CONTROL METHOD OF FLUID PRESSURE ACTUATOR
Document Type and Number:
Japanese Patent JPS59121201
Kind Code:
A
Abstract:
PURPOSE:To accurately control a loading device so that it can be guided to a position corresponding to an instructed value, even if a preset position of a detector for detecting the operating position of a fluid actuator is not accurately determined. CONSTITUTION:A voltage generator 21 is arranged so that it is positively returned and set to its zero position as the operator moves his hand away from the generator 21. At such a point of time immediately after the power switch of a control system is turned on, a computer 20 is caused to memorize a difference between a command signal value and a feedback signal value as an error value dFB. After the operator begins to operate the voltage generator 21, a feedback signal value is corrected by the dFB.
