Sampled Closed-Loop Game based Attitude Control for On-orbit Assembly

In this paper, we investigate the on-orbit assembly problem under intermittent measurements. The main challenge of this problem is how to produce practical control torques for multiple microsatellites to regulate the attitude of combination against limited measurements. Toward this, we introduce the attitude dynamics of combination, of which the attitude control torques are determined by microsatellites fixed on the surface. In addition, a sampled closed-loop game strategy is first introduced for multiple microsatellites attitude adjustment, where the strategy requires only intermittent and inherent-frequency measurements. The existence of saddle point has been proven rigorously in the underlying problem. Finally, simulation results verified the performance of the proposed strategy.
