This brief investigates the finite-time control problem associated with attitude stabilization of a rigid spacecraft subject to external disturbance, actuator faults, and input saturation. More specifically, a novel fixed-time sliding mode surface is developed, and the settling time of the defined surface is shown to be independent of the initial conditions(More)
In this paper, a finite-time control method based on fixed-time is developed for attitude stabilization of a rigid spacecraft with external disturbances. In comparison with the existing finite-time techniques based on terminal sliding mode, of which the initial value of system states must be known when estimating the settling time, the proposed fixed-time(More)
