Titel
Smart neuro-fuzzy based control of a rotary hammer drill
Abstract
In order to reach an optimal drill effect by using a rotary hammer, it is necessary to control the two variables rotational speed and strike rate of the rotary hammer in such a way that by applying minimal guidance and recoil power a maximal drill speed in the stone hole can be achieved. An optimal drill speed is attained for a certain combination of rotational speed and strike rate. Alterations of drill diameter and/or material hardness lead to a false adjustment of the system which has to be re-optimized by an intelligent re-adjustment of the two servo- controlled drives. For achieving a flexible and automatic adaptation of rotational speed and strike rate of the rotary hammer to altered material and tool types, an adaptive multi-sensoric drive control upon the base of a self-learning neuro-fuzzy component has been developed by IITB in co-operation with an industrial partner.
