TLDR
An observer-based fault-tolerant control scheme is proposed for the attitude stabilization of rigid spacecraft in the presence of actuator fault, configuration misalignment, input saturation and even external disturbances simultaneously and can be guaranteed theoretically to be stable by the development of Lyapunov methodology.About:

Resolving actuator redundancy: optimal control vs. control allocation
Ola Härkegård,S. Torkel Glad +1 more
TL;DR: In this article, the authors investigate the relationship between optimal control design and control allocation when the performance indexes are quadratic in the control input and show that for a particular class of nonlinear systems, they give exactly the same design freedom in distributing the control effort among the actuators.

Integral sliding mode in systems operating under uncertainty conditions
Vadim I. Utkin,Jingxin Shi +1 more
TL;DR: The paper generalized a new sliding mode design concept, namely integral sliding mode (ISM), and removes the discontinuous control action from the real control path and inserts it to an internal dynamic process for generating the sliding mode to alleviate chattering.

Fault tolerant control using sliding modes with on-line control allocation ☆
Halim Alwi,Christopher Edwards +1 more
TL;DR: In this paper, an on-line sliding mode control allocation scheme for fault tolerant control is proposed, where the effectiveness level of the actuators is used to redistribute the control signals to the remaining actuators when a fault or failure occurs.
