Attitude Control of Underactuated Multibody Spacecraft
نویسندگان
چکیده
A three dimensional reorientation problem for an underactuated multi-body spacecraft is studied. Formulae for approximating the change in orientation of the base body of the spacecraft, induced by appropriately constructed small amplitude periodic joint motions, are derived. These formulae are used to construct joint motions that cause a desired reorientation maneuver to be performed within a prescribed accuracy. The computation of these joint motions requires solving a system of simple linear algebraic equations and can be eeciently implemented on-line.

New Control Strategies for Underactuated Tethered Formation Flight Spacecraft
We introduce a decentralized attitude control strategy that can dramatically reduce the usage of propellant, by taking full advantage of the physical coupling of the tether. Motivated by a controllability analysis, indicating that both spin-up and relative attitudes are fully controllable by the reaction wheels, we report the first propellant-free underactuated linear and nonlinear control resu...
متن کاملControl of underactuated spacecraft with bounded inputs
We provide stabilizing feedback control laws for the kinematic system of an underactuated axisymmetric spacecraft subject to input constraints. The proposed control law forces all closed-loop trajectories in a region of the state space where the control inputs are small and bounded. The control law is subsequently extended to solve the case of attitude tracking for an underactuated spacecraft u...
متن کاملAttitude Control of an Underactuated
A continuous feedback controller with a periodic time varying term for the attitude control of an un-deractuated rigid spacecraft is derived. The attitude is described with the Euler parameter vector. Due to the nondiierentiable nature of exponential stabilizers , sampling of some measurements is used. Global exponential convergence is indicated with analysis and simulations.

We provide stabilizing and tracking feedback control laws for the kinematic system of an underactuated axisymmetric spacecraft subject to input constraints. As a special case we also provide a feedback control to track a specified direction in inertial space. All proposed control laws achieve asymptotic stability with exponential convergence. One of the novelties of the proposed control design ...
متن کاملPropellant-Free Control of Tethered Formation Flight, Part 2: Nonlinear Underactuated Control
This is the second in a series of papers that exploit the physical coupling of tethered spacecraft to derive a propellant-free spin-up and attitude control strategy. We take a nonlinear control approach to underactuated tethered formation flying spacecraft, whose lack of full state feedback linearizability, along with their complex nonholonomic behavior, characterizes the difficult nonlinear co...
