研究了基于四元数的卫星编队飞行有限时间姿态同步与稳定问题。给出了该分布式一致性问题的有限有界性和稳定性的充分条件。具体地说，提出了一种基于有限时间控制技术的非线性控制律，使刚体飞行器的姿态在有限时间内协调并收敛于前导飞行器的姿态，角速度收敛于零。相关的稳定性证明是建设性的，并通过在李雅普诺夫函数中加入一个幂积分项来完成。此外，为了减轻沉重的通信负担，通过引入有限时间滑模估计器，设计了一种改进的控制律，使得只有一个卫星必须与领头羊通信。仿真结果证明了所设计方案的有效性，特别是通过包含…
This paper investigates a quaternion-based finite time attitude synchronization and stabilization problem for satellite formation flying. Sufficient conditions are presented for finite time boundness and stability of this distributed consensus problem. More specifically, a nonlinear control law based on a finite time control technique is developed such that the attitude of the rigid spacecraft will coordinate and converge to the attitude of the leader, while the angular velocity will converge to zero in finite time. The associated stability proof is constructive and accomplished by adding a power integrator term in the Lyapunov function. Furthermore, to reduce the heavy communication burden, a modified control law is then designed by introducing a finite time sliding-mode estimator such that only one satellite has to communicate with the leader. Simulation results are presented to demonstrate the effectiveness of the designed scheme, especially the potential advantages derived through the inclusion of the...
