Title:
CONTROLLING METHOD OF HYDRAULIC ACTUATION TYPE WORKING MACHINE
Document Type and Number:
Japanese Patent JPS6275104
Kind Code:
A
Abstract:
PURPOSE:To carry out the action control of a working machine, by detecting the parameter variation of a controlled object, and correcting a controlling instruction value for a hydraulic valve based on the intended input of the working machine corresponding to the parameter variation. CONSTITUTION:A parameter identification device 19 has the arithmetic unit 24 of a parameter variation which calculates the difference of the mathematical model 23 of a controlled object 22 and an actually observed value when a control instruction based on the controlled object is inputted. This calculated result is inputted to a feedback gain calculator 20 and a correcting instruction is inputted to a controller 18 therefrom, so that a controlling instruction value is corrected corresponding to the parameter variation. Thereby, the action of a working machine can be controlled accurately on a working position corresponding to the intended input of the working machine.
