IAA-AAS-DyCoSS2 -10-04 BACKSTEPPING ATTITUDE COORDINATION CONTROL FOR SPACECRAFT FORMATION WITH MULTIPLE DELAYS
نویسندگان
چکیده
This paper addresses attitude coordination control for spacecraft formation with multiple delays. A distributed angular velocity input law is firstly constructed for attitude synchronization and tracking under multiple communication delays. Introducing virtual auxiliary systems makes it possible to integrate the angular velocity input law with the true true control torque, and asymptotic stability of the system is guaranteed by Lyapunov theory. Moreover, by modifying the angular velocity input law, attitude coordination among spacecrafts can be guaranteed even under control input saturation constraints. Finally, effectiveness of the proposed methodology is illustrated by concrete simulations.

In this paper, we analyze dynamics of a DGVSCMG(Double-Gimbal VariableSpeed Control Moment Gyro) and develop an easy-to-use LPV (Linear ParameterVarying) model, in which we deal with 3-axis attitude control of a spacecraft equipped with a DGVSCMG. Although it is hard to consider overall stability and control performance of attitude control at the same time with conventional methods, this paper ...

This paper is to investigate the coordinated attitude control problem for flexible spacecraft formations. Considering the attitude maneuver control problem of a formation composed of flexible spacecraft, two classes of decentralized attitude coordination control laws using behavior-based control approach are proposed. The first class of controllers can steer the attitude states of the flexible ...

The Distributed Spacecraft Attitude Control System Simulator is a testbed comprised of two independent spherical air-bearing platforms, useful for formation-flying attitude control simulation. The DSACSS is intended to support a wide range of functions. As such, requiring that all controllers be robust to approximations of the system parameters is impractical. We document the development of bat...
