| Summary: | In future space missions, cooperative attitude control is required for essential tasks with multiple spacecraft, such as satellite constellations. In recent years, spacecraft have increased in size and weight, necessitating infinite-dimensional systems. This paper discusses a leader-follower attitude consensus control of a multiagent system with multiple flexible spacecraft. Each flexible spacecraft consists of two flexible structures and a rigid hub, and its dynamic behavior is given by a hybrid PDE-ODE model. For this controlled system, to achieve attitude consensus control and suppress the elastic vibration of the system simultaneously, we propose a distributed boundary controller and show that the controller exponentially stabilizes a closed-loop system. We also investigate the closed-loop system’s stability in the context of varying communication topologies and in the presence of disturbances. Finally, we carried out numerical simulations to validate the effectiveness of the proposed controller. |
