Spacecraft Attitude Tracking Control
The problem of reorienting a spacecraft in to acquire a moving target is investigated. The spacecraft is modeled as a rigid body with N axisymmetric wheels controlled by axial torques, and the kinematics are represented by Modified Rodriques Parameters. The trajectory, denoted the reference trajectory, is one generated by a virtual spacecraft that is identical to the actual spacecraft. The open...
متن کاملAngular Velocity-Free Control for Rigid Spacecraft Attitude Stabilization under Input Constraint
A novel attitude stabilization control scheme is presented for rigid spacecraft. As a stepping stone, a first-order passivity filter is proposed to generate a velocity-related signal from attitude measurements. Then, a velocity-free attitude stabilization controller is synthesized by using a hyperbolic tangent function. It is shown that the controller render the equilibrium points in the closed...
متن کاملDecentralized attitude alignment control of spacecraft within a formation without angular velocity measurements ⋆
Abstract: In this paper, we consider the coordinated attitude control problem without velocity measurements. Based on the recently introduced unit quaternion output feedback for the attitude tracking of a rigid body, we present a class of decentralized coordinated control laws to solve the alignment problem for a group of spacecraft within a formation without velocity measurements. The approach...
متن کاملCoordinated Attitude Control of Spacecraft Formation Without Angular Velocity Feedback: A Decentralized Approach
In this paper, motivated by recent developments of velocity-free spacecraft (SC) attitude control techniques and behavioral-based SC formation control a decentralized control algorithm for attitude coordination of SC formation without angular velocity feedback is presented. Asymptotic stability of the SC formation is guaranteed by using Lyapunov analysis and LaSalle’s theorem. The advantage of ...
متن کاملAttitude Tracking Control for Spacecraft Formation Flying
We develop a non-linear tracking control law to be applied to formation flying spacecraft. Each spacecraft in the formation is modeled as a rigid body with N axisymmetric wheels controlled by axial torques, and the kinematics are represented by Modified Rodriques Parameters (MRPs). The paper first derives the open-loop reference attitude, rate, and acceleration commands for tracking a moving ob...
