The Finite-time Robust Control for Spacecraft Rendezvous and Docking

摘要：

　　In this paper,the problem of relative position control for rigid spacecraft in rendezvous and docking is investigated.We propose a control scheme with finite-time convergence based on the linearized dynamic model obtained from the Hill-Clohessy- Wiltshire (HCW) equations,in the presence of external disturbance.By constructing a particular Lyapunov function,we confirm the convergence of the proposed controller theoretically.Furthermore,to alleviate the chattering phenomenon while at the same time guaranteeing the finite-time convergence,we introduce a new function into the controller.Finally,simulation results are presented to elucidate the effectiveness of the control strategy.
