Title:
CONTROLLING METHOD OF HYDRAULIC ACTUATION TYPE WORKING MACHINE
Document Type and Number:
Japanese Patent JPS6275106
Kind Code:
A
Abstract:
PURPOSE:To carry out the action control of a working machine without time lag, by controlling it with feeding back by the variation of the internal factor of a control system influencing the working precision of the machine. CONSTITUTION:In addition to the target figure alphao of a boom angle from a first setting device 16, the target values of the internal factor of a control system which influence the working precision of the boom, for example, a target flow Qo, the variation Qo' of the target flow and the like are inputted corresponding to an inputted arm angle beta. And respective target control values and detected values are controlled with feeding back. Thereby, the time lag which extends from the target figure of the boom angle being inputted till the boom coming to a position corresponding to the target figure of the boom angle is reduced, and the working precision is improved.
