Steering law considering biased loads for control moment gyroscopes
Mechanical Engineering Journal, 2015 A new steering law of a pyramid configuration of four control moment gyroscopes (CMGs) is proposed to suppress radical motion of gimbals, reduce the gimbal angular displacement and level the biased ones of the four CMGs.
