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: The flight pose of an aircraft is affected seriously by the stress-deflection angles of aileron and tail fin. Traditional manual measurement suffers from ...
