Observer-Based Finite-Time Attitude Containment Control of Multiple Spacecraft Systems

Abstract

In this brief, the output feedback based finite-time attitude containment control problem for multiple spacecrafts is investigated. A novel finite-time command filtered backstepping containment control scheme is proposed for attitude systems with unmeasurable states, inertia uncertainties, external disturbances and input saturations, which can not only guarantee the containment control errors converge to the sufficient small neighborhood of the origin in finite-time, but also overcome the computation complexity problem in traditional backstepping. The simulation results show the effectiveness of the proposed control scheme.
