Event-triggered Attitude Tracking Control of Spacecraft Formation with Prescribed Performance

This paper is developed for attitude tracking control of spacecraft formation to reduce the communication burden. Based on the backstepping technology and prescribed performance function, a new adaptive distributed event-triggered control law is proposed which possesses the following properties: 1) The communication burden of formation is reduced for only the attitude information of the neighbors is required to be exchanged. 2) The communication burden is further reduced by employing a event-triggered mechanism, which only sends the sampling states at the event-triggering instants to the control module. 3) Attitude tracking errors can converge to predefined arbitrarily small residual sets. Finally, A simulation example is employed to verify the effectiveness of the proposed control scheme.
