Position and attitude control of a spacecraft by sliding mode control

Robust optimal sliding mode control for spacecraft position and attitude maneuvers

“…The dynamics of a 6-DOF spacecraft which performs translational and rotational maneuvers can be modeled by [49]:…”

“…Section 2 introduces some preliminary results which are required for the following discussion. In Section 3 the dynamics and kinematics of spacecraft with coupled translation and attitude dynamics [48], [49] are described. The problem statement and control objective are also given.…”

Relative motion coupled control for formation flying spacecraft via convex optimization

“…(19) and (20). The generic norm constraint, representing a constrained sphere, generally concerns the overall error, while the terminal box constraint deals with 3-axis error.…”

“…The study of dynamics and control with coupled translational and rotational dynamics has received scant attention in the current literature except Refs. [14,20,19] and [16]. In Ref.…”

“…[20], an output feedback tracking control law with a high-pass filter employed to estimate the relative velocities is designed based on mutually coupled translational and rotational dynamics of formation flying spacecraft. Some other methods, including sliding mode control [19] and state-dependent Riccati equation method [16], are used to control the spacecraft position and attitude to maneuver around tumbling space debris. Furthermore, an adaptive nonlinear controller was developed with unknown mass and inertial parameters in Ref.…”
