N2 - The finite time control for proximity to target spacecraft is investigated in this paper. The relative motion dynamics for the chaser spacecraft and target spacecraft is firstly proposed. Then a finite time controller, based on a novel fast terminal sliding mode approach, is designed to achieve above control objective. The stability and convergence of the closed-loop system with the property of finite time are discussed by Lyapunov method. The escape maneuver of target spacecraft is further considered, and an observer-based modified finite time controller is proposed to deal with this problem. Numerical simulations are finally provided to illustrate the performance of the proposed controllers.
