Equivalent-input-disturbance based rotating control of drill-string in compound directional drilling process subject to coal seam variation

ISA Transactions
Coal seam variations in coal mine drilling can cause fluctuations in feed speed and rotational speed of the rotary head (ROR), reducing the performance of compound directional drilling control systems. This paper addresses these issues by considering the change in intrinsic specific energy caused by coal seam variations as a disturbance.
