Attitude consensus control of multiple flexible spacecrafts

This paper studies the attitude consensus control and vibration reduction of multiple flexible spacecrafts. For the multiple flexible spacecrafts with a communication topology represented by a directed and connected graph, a distributed boundary-based control scheme is designed to achieve the attitude consensus while reducing the vibrations of each flexible appendage. Using the LaSalle’s invariance principle, the asymptotic stability of multiple flexible spacecrafts is proven. Simulations verify the feasibility of the designed strategy.
