Abstract
This study investigates the finite-time attitude-tracking problem for rigid spacecraft. A novel non-singular terminal sliding-mode control (NTSMC) law is designed to provide finite-time convergence and fast, high control precision even though inertia uncertainties and external disturbances affect the spacecraft systems under actuator failures and saturations. The proposed NTSMC scheme is chattering suppression and singularity-free. Simulation results are presented to demonstrate the efficiency of the proposed method.
