In this paper, the attitude tracking control problem is investigated for a rigid spacecraft. Robust finite time controllers based on the quaternion and Lagrange-like model are proposed to solve this problem with model uncertainties and external perturbations. The controllers guarantee the convergence of attitude tracking errors in fixed time, where the settling time can be set in advance, and this merit is different from all the existing controllers for spacecraft attitude tracking problem.
