TL;DR: A novel fault tolerant attitude tracking control scheme is developed for flexible spacecraft with partial loss of actuator effectiveness fault and it is shown that the roll, pitch and yaw angle trajectories can globally asymptotically track the desired attitude in the face of faulty actuator, system uncertainties, external disturbances and even actuator saturation.

TL;DR: In this article, a velocity-measurement-free feedback control problem associated with attitude tracking for a rigid spacecraft in the presence of both actuator failures and actuator saturation is investigated.

TL;DR: A practical solution is presented to the problem of fault tolerant attitude stabilization for a rigid spacecraft by using feedback from attitude orientation only and the derived controller not only has the capability to protect the control effort from actuator saturation but also guarantees all the signals in the closed-loop system to be uniformly ultimately bounded.

TL;DR: A finite-time attitude tracking control scheme is presented for rigid spacecraft subject to constant but unknown inertia and external disturbances and guarantees the desired attitude to be followed in finite time, which is critical for FTC systems.

TL;DR: In this paper, the authors proposed a fault-tolerant attitude stabilization controller without velocity magnitude in the presence of two types of actuator faults, which can guarantee the attitude control performance greatly robust to external disturbances and unknown inertia parameters.
