Error Dynamics Based Dual Heuristic Dynamic Programming for Self-Learning Flight Control
Applied Sciences, 2022 A data-driven nonlinear control approach, called error dynamics-based dual heuristic dynamic programming (ED-DHP), is proposed for air vehicle attitude control. To solve the optimal tracking control problem, the augmented system is defined by the derived

Attitude control of a tethered spacecraft
Proceedings of the 2003 American Control Conference, 2003., 2004 An attitude control problem for a tethered spacecraft is studied. The tethered spacecraft is viewed as a multi-body spacecraft consisting of a base body, a massless tether that connects the base body and an end mass, and tether actuator dynamics. Moments about the pitch and roll axes of the base spacecraft arise by control of the point of attachment of

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.

Attitude Control of Two-Wheel Spacecraft Based on Dynamics Model via Hierarchical Linearization
SICE Journal of Control, Measurement, and System Integration, 2017 In this paper, we propose an attitude control law for underactuated two-wheel spacecraft under non-zero total angular momentum. Attitude control with non-zero total angular momentum is complicated in the case that the number of reaction wheels equipped ...
