Abstract In this paper, two finite-time attitude coordinated controllers for formation flying spacecraft are investigated based on rotation matrix. Because rotation matrix can represent the set of attitudes both globally and uniquely, the two controllers can deal with unwinding that can result in extra fuel consumption. To address the lack of angular velocity measurement, the second attitude coordinated controller is given by using a novel filter. Through homogeneous method and Lyapunov theories, it is shown that the proposed controllers can achieve the finite-time stability. Numerical simulations also demonstrate that the proposed control schemes are effective.

    Highlights We investigate two finite-time attitude coordinated controllers based on the rotation matrix. The first finite-time controller without unwinding is proposed by homogeneous method. The second finite-time output feedback coordination controller is given by using a novel filter. The region of attraction does not need to consider during the controller design.
