Model-based Coordination Control of Networked Spacecraft Formations by Integrator Backstepping

摘要：

In this paper,based on the leader-follower formation architecture,we propose a tracking control scheme for space-craft formation ying 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 uni-formly ultimate boundedness (UUB)of the relative position and velocity tracking errors in the semiglobal sense.The adjustable parameter with respect to which semiglobal UUB is achieved is the network access deadline between transmission times.Nu-merical simulations are presented to demonstrate the effectiveness of the developed controller.
