Box 294, Bussum, 1400 AG, Netherlands Abstract: Severe environment in deep ocean affects operating reliability and security of coring drill. Adopting heave motion signal measured by accelerometer to confirm heave compensation of coring drill, the compensation control method is proposed using disturbance observer to restrain the disturbance. Then, the disturbance observer is designed. The heave motion simulation for coring drill is done with this control method, and the results show that the heave motion compensation control of coring drill using disturbance observer avoids the disturbance with high tracking quality, and provides high reliability and security to coring drill operating. © Guo et al.
