Abstract :
In this paper, we propose two finite-time control laws for rigid spacecraft. We use quaternion for attitude representation and employ the Lagrange-like model for convenience of system design. First, by using the finite-time control method, a full-state feedback control scheme is presented. Then, considering no angular velocity measurement can be obtained, we propose a finite-time control law. Under the proposed control laws, the attitude of spacecraft converge to desired attitude in finite time.
