AUTOMATIC DISPLACEMENT CORRECTION METHOD AND DEVICE FOR EXCAVATOR AND CONTROL METHOD OF EXCAVATION SPEED

摘要

PURPOSE: To provide a method and device for properly controlling an automatic displacement correction of an excavator capable of automatically correcting displacement from a target of the excavator to control and excavation speed thereof without being influenced by ability, etc., of an operator. ;CONSTITUTION: The fuzzy theory is applied to displacement from a control target of the position of an excavator 5 and variation rate of the displacement during the excavation, expansion of a jack section 25 is controlled every specific short period and, at the same time, the fuzzy theory is applied to mean value of displacement and positive and negative code inversional frequency to control expansion and contraction of the jack section 25 every long period longer than the short period. According to the constitution, control performance varied from moment to moment is estimated from a control result by a displacement correction control section 37, gain is adjusted by a gain adjustment control section 38, and a control amount (an expansive control amount of the jack section) derived from the displacement correction control section is corrected.;COPYRIGHT: (C)1994,JPO
