This paper addresses the prescribed time performance attitude tracking control problem of un-manned aerial vehicles under unknown attacks and input saturation. The attitude error dynamic model is constructed under the framework of Lie group SO(3). By integrating a prescribed time performance function with coordinate transformation, the tracking error can remain within a given region in a prescribed time. In the backstepping design process, a first-order sliding mode differentiator is given to overcome the explosion of complexity problem, and nonlinear disturbance observer is developed to deal with the unknown attacks and input saturation. A prescribed time performance attitude tracking control method is designed to ensure that all of the closed-loop signals are bounded. Finally, the superiority and effectiveness of the designed controller are stated by the simulation results.
