Abstract
This article considers the attitude tracking control problem for rigid spacecraft with external disturbances and model uncertainties. An attitude controller with prescribed time and prescribed error bound is proposed based on scaling-transformation and backstepping. The controller can drive the attitude tracking error of the spacecraft to converge into the prescribed bound around the origin before the prescribed time with nonsingular and continuous torque. Numerical simulations are carried out to evaluate the performance of the proposed controller.
