Using a downhole motor with bent housing most effectively requires determination of its deflecting performance and designing the bottom hole assembly according to the expected deflection rate.

Abstract: In this paper, a composite anti-disturbance control method is proposed for electromechanical fin actuators with deflection angle constraints and multiple disturbances. Firstly, a ...

Abstract: We present results for motion planning and tracking for flexible beams with Kelvin-Voigt damping, when the goal is to track sinusoidal reference signals for the displacement and deflection ...
