Abstract

This paper presents a fixed-time nonsingular terminal sliding mode control methodology for spacecraft rendezvous in the presence of nonlinearity and external disturbance. A nonsingular terminal sliding surface is constructed and a continuous sinusoidal function is introduced into the controller to solve the inherent singularity problem. Under the proposed controller, the relative position of the chaser spacecraft can rendezvous with the target within fixed time, which is demonstrated by Lyapunov theorem. The simulation results show that the proposed controller enables rapid convergence rate, high precision and strong robustness in the presence of nonlinearity and external disturbance.
