Event-triggered Attitude Tracking Control of Spacecraft Formation with Prescribed Performance
Tao Guan, Kai Zhang, Shuping Tan, Bin Li · 2023
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.
