Abstract Directional Steering System (DSS) has been established for well drilling in the oilfield in order to
accomplish high reservoir productivity and to improve accessibility of oil reservoirs in complex
locations. In this paper, a novel feedback linearization controller to cancel the nonlinear dynamics of a
DSS is proposed. The proposed controller design problem is formulated as an optimization problem for
optimal settings of the controller feedback gains. Gravitational Search Algorithm (GSA) is developed to
search for optimal settings of the proposed controller. The objective function considered is to minimize
the tracking error and drilling efforts. More >
