Abstract

This study addresses the prescribed-time anti-unwinding attitude tracking control problem for a rigid spacecraft. First, a prescribed-time sliding mode disturbance observer is designed to estimate the disturbances. To ensure prescribed-time convergence and avoid the unwinding phenomenon, a new prescribed-time sliding mode surface is established by introducing a hyperbolic sine function such that the designed sliding surface includes two equilibrium points. Subsequently, an attitude tracking control law with a disturbance compensation term is designed to guarantee that the system states converge to the sliding surface in a prescribed-time. The simulation results reveal that anti-unwinding prescribed-time attitude tracking of a rigid spacecraft can be achieved by using the developed attitude control law.
