Non-Singular and Continuous Back-Stepping Predefined-Time Attitude Tracking Control for Rigid Spacecraft with Predefined Bound
In this paper, we consider the attitude tracking control problem for rigid spacecraft with external disturbances and model uncertainties. An attitude tracking predefined-time controller with predefined bound is proposed based on back-stepping. The controller can make the attitude error of spacecraft converge into a predefined bound within the predefined time with continuous and non-singular torque. Numerical simulations are carried out to illustrate the effectiveness of the controller proposed.
