52.インドネシアのオンビリン炭鉱におけるオンライン灰分計を用いたジグ選別機の自動制御

抄録

For the rehabilitation of a coal preparation plant at Ombilin Coal Mine in Indonesia, we have focused on the establishment of a system that is capable of automating the current type of quality control system and of controlling them on-line. The way in which this is achieved is to measure the ash content of the float products from jig separator continuously in an on-line fashion so as to control jig operation in accordance with the signal output We try to model the jig operation to develop a control system using fuzzy modeling. This system permits efficient quality control of the float products from the jig and resolves the problems of unsteady control.
