A novel control approach is illustrated in this work for uncertain nonlinear systems to guarantee precise tracking behavior with prescribed performance when faced any initial conditions. Wherein, the prescribed performance method is employed so that the output tracking error could attenuate to a vicinity around zero within the appointed-time. Then, a high-gain extended state observer is constructed to acquire the estimations of the unknown system signals. With the aid of observer estimations, a novel output feedback tracking control algorithm is presented, relying upon the backstepping framework. It has been demonstrated that the output tracking error reaches the predesigned performance requirements during the tracking process. Furthermore, the boundedness of all system signals is deduced according to a Lyapunov-based stability synthesis. Finally, applications to a spacecraft attitude system are presented to illustrate the theoretical findings.
