摘 要：正In this paper,based on the leader-follower formation architecture,we propose a tracking control scheme for spacecraft formation flying in the framework of networked control systems（NCSs） with time-varying network access intervals.A continuous-time representation of the NCS is considered to model the relative translational motion of the follower spacecraft relative to the leader spacecraft.A model-based controller combined with backstepping technique is developed to guarantee uniformly ultimate boundedness（UUB） of the relative position and velocity tracking errors in the semiglobal *** adjustable parameter with respect to which semiglobal UUB is achieved is the network access deadline between transmission *** simulations are presented to demonstrate the effectiveness of the developed controller.
