“…In the past several decades, the attitude control problem of spacecraft has attracted a great deal of attention due to its important applications [1][2][3]. As actuation devices generate toques with only limited amplitude and/or rate [4][5][6], input saturation may frequently occur during the entire attitude maneuvers of a spacecraft.…”

Fault-tolerant constrained attitude controllers are proposed for flexible spacecraft in the presence of input saturation and actuator fault, as well as model uncertainty and external disturbance. Two input saturations, that is amplitude saturation and, amplitude and rate saturation are considered and simple and effective compensators are designed to deal with the effect of input saturation. Two parameter update laws are designed to endure stuck fault, partial and complete loss of effectiveness fault. The stability of the resulting closed-loop systems by the proposed controllers is guaranteed by Lyapunov-based approach. The effectiveness of the proposed algorithms is assessed through numerical simulations.

“…For TSMC, nonlinear sliding 2 International Journal of Aerospace Engineering surface was proposed and the finite-time convergence was analyzed based on the concept of terminal attractor. TSMC has been applied to spacecraft attitude control problems [20][21][22]. Later, a nonsingular terminal sliding mode based robust finite-time control law was proposed in [23,24] to deal with the singularity problem, which exists in traditional TSMC.…”

This paper investigates the fixed-time attitude tracking control problem for flexible spacecraft with unknown bounded disturbances. First, with the knowledge of norm upper bounds of external disturbances and the coupling effect of flexible modes, a novel robust fixed-time controller is designed to deal with this problem. Second, the controller is further enhanced by an adaptive law to avoid the knowledge of norm upper bounds of external disturbances and coupling effect of flexible modes. This control law guarantees the convergence of attitude tracking errors in fixed time where the settling time is bounded by a constant independent of initial conditions. Moreover, the proposed controllers can prevent the unwinding phenomenon. Simulation results are presented to demonstrate the performance of the proposed control scheme.

“…In [7], robust finite-time controllers are proposed for spacecraft attitude tracking based on quaternion and terminal sliding mode (TSM). In [8][9][10], fast TSM and adaptive laws are employed to solve attitude stabilization or tracking problem.…”
