This paper considers the problem of attitude synchronization for a group of flexible spacecraft based on distributed attitude cooperative control strategy. Based on the backstepping design, non-smooth control, and the neighbor-based design rule, a distributed attitude control law is constructed step by step. Under the proposed control law, it is shown that the attitude synchronization is achiev...

Optimal controller design approach for high precision pointing maneuver of flexible spacecraft by using adaptive structures is investigated in this paper. A parameter optimization technique is used to find out controller parameters minimizing a desired objective function which represents pointing performance of a flexible space structure. Multi-input and multi-output configuration used in this ...

Abstract. This work is focused on some recent advances spacecraft dynamical modeling and attitude control. First, the problem of correctly linearizing elastic behavior spinning flexible discussed, an example presented that addresses this topic from both analytical numerical point view. Then, control considered a new feedback law for single axis alignment presented, together with inclusion accur...

In this paper, a closed-loop switching function for on-off thruster firings is proposed to provide good attitude control performance in the presence of modeling errors for single-axis slew maneuver of a rigid spacecraft and to eliminate double-sided thruster firings. The size of a single-sided deadband in the switching function provides the capability of a tradeoff between maneuver time and fue...
