This paper investigates the finite-time output feedback problem of attitude tracking control for spacecraft. It is assumed that the angular velocity information is not available for the controller design. An adding a power integrator technique based filter is designed to generate the pseudo-angular-velocity estimates, then a finite-time output feedback attitude tracking controller is developed with relative-attitude-only measurement. Overall finite-time stability of the entire closed-loop system is given, which shows the attitude tracking errors will converge into a region of zero in the presence of external disturbance. The simulation results illustrate the highly precision and robust attitude control performance of the proposed controllers.
