Coordinated Control of Satellites: the Attitude Case
نویسندگان
چکیده
In this paper an observer-controller structure for attitude synchronization of a satellite formation is presented. The design applies methods from mechanical synchronization to design a nonlinear observer and controller for satellites actuated by means of reaction wheels and magnetic torquers. In this approach one satellite is defined as the leader of the formation, while the rest are defined as followers which synchronize their attitude with the leader. We apply the approach to the design of an coordinated attitude control scheme for a two-satellite formation. In addition we propose a momentum dumping scheme for satellites with redundant reaction wheel assemblies.

Dynamic Modeling for Earth – Pointing Satellites to Control the Three – axis Attitude without the Attitude Information of One Axis
Various methods are presented to control the attitude of satellite due to lack of information of yaw axis attitude so far. In this paper, a new method is used which is more general and is applicable to all types of satellites, with at least one controller. This method is not limited to YAW axis and can control the two other axes as well. One feature of this approach is the ability to be modi...

متن کاملTracking Control of Uncertain Non - Iinear MIMO System Using Modified Sliding Surfaces for Attitude Large Maneuver of Satellites on Orbit
Designing a robust tracking control for a non-linear MIMO system with uncertainty is one of the most complicated control problems. In this paper, sliding mode changed to non-linear controllable canonical form by input-output linearization. This, sliding surfaces can be defined in a way that we can de-couple equations and indicate the sliding conditions of multi-variable controller system. The u...

متن کاملAttitude Synchronization Control in Satellite Formation Flying in the Presence of States Measurement Errors
This paper presents a novel attitude synchronization framework for tracking control of multiple identical/heterogeneous satellites in formation flying with connected communication graph. The main contribution of the paper is considering sensors' measurement error to derive control gains. Moreover, the proposed strategy need no angular velocity communication. Nevertheless, the tracking synchroni...
