The problem of finite-time attitude regulation for multiple rigid spacecraft with leader–follower architecture is studied. The desired attitude for spacecraft formation is represented by the attitude of a leader. A distributed finite-time convergent observer is first proposed to estimate the leader’s attitude in a finite time. By using the technique of finite-time saturation control, a bounded finite-time...
The problem of attitude regulation for a rigid spacecraft under input saturation is studied in this paper. Based on the technique of finite-time control and the model structural features, a novel finite-time attitude controller is proposed. The bound of a proposed finite-time controller can be adjusted to any small level to accommodate the actuation bound in practical implementation. A simulation...
