Adaptive Asymptotic Tracking of Spacecraft Attitude Motion with Inertia Matrix Identification
TL;DR: The problem of a spacecraft tracking a desired trajectory is addressed and addressed using adaptive feedback control using a sixth-order dynamic compensator and a Lyapunov argument is used to show that tracking is achieved globally.

Optimal distributed control of a flexible spacecraft during a large-angle maneuver
James D. Turner,Hon M. Chun +1 more
TL;DR: The solution of the necessary conditions obtained from Pontryagin's principle for the problem of optimal large-angle single-axis maneuvers of a flexible spacecraft possessing a distributed control system is discussed.

Quadratically constrained attitude control via semidefinite programming
Yoonsoo Kim,Mehran Mesbahi +1 more
TL;DR: By utilizing the implicit magnitude constraint of the state vector, this work is able to reduce the attitude control problem to a convex quadratically constrained quadratic program or a semidefinite program, leading to an efficient solution strategy for general quadrally constrained attitude control problems.
Journal ArticleDOI
On the Convex Parameterization of Constrained Spacecraft Reorientation
TL;DR: In this article, convex parameterizations of sets associated with the constrained rigid body orientations are considered for autonomous spacecraft reorientation, and an algorithm based on convex optimization is proposed for constrained multiple spacecraft re-orientations.
Journal ArticleDOI
Nonlinear Adaptive Attitude Control of Spacecraft
TL;DR: In this article, a model reference adaptive control law is presented for large-angle rotational maneuvers of spacecraft using reaction jets, assuming that the various parameters of the spacecraft are completely unknown, and unknown but bounded disturbancetorques are acting on the spacecraft.

Method of Gradients
TL;DR: In this paper, the authors discuss the main features of the gradient method in the context of ordinary minimum problems subject to constraints, and discuss the variational problems of flight performance, introducing Green's functions in the role played by partial derivatives in ordinary minimax problems and attempting to preserve an analogy between the two classes of problems in subsequent development.
Journal ArticleDOI
Quaternion from Rotation Matrix
TL;DR: In this article, a quaternion is regarded as a four-parameter representation of a coordinate transformation matrix, where the four components of the quaternions are treated on an equal basis.

Perturbation Solution for the Flat Spin Recovery of a Dual-§pin Spacecraft
Jean R. Gebman,D. Lewis Mingori +1 more
TL;DR: In this paper, Euler's differential equations for free-body attitude motion were solved for the constant bearing axis torque recovery maneuver of a spacecraft with a symmetric rotor and asymmetric platform.

Equivalence of the Minimum Norm and Gradient Projection Constrained Optimization Techniques
TL;DR: In this paper, it was shown that for a > 10 Alien's approximate solution, as given by Eq. (12), provides an excellent approximation to his differential equation for the straight line descent of a large drag ballistic missile.

Adaptive spacecraft attitude control utilizing eigenaxis rotations
TL;DR: In this paper, conventional and adaptive attitude control of spacecraft which use control moment gyros (CMG's) as torque sources are discussed, and a Model Reference Adaptive System (MRAS) controller based on Liapunov's Second Method is adopted.
