Decentralized Fault-Tolerant Control for Satellite Attitude Synchronization

Robust fault-tolerant cooperative control of multi-agent systems: A constructive design method

“…As actuator faults might occur during the operation of multiple agent systems, several researchers [23], [24] have explicitly addressed this issue by considering the additive (bias) faults only, which corresponds to b i (t) = 1. In this work a more general thus more involved case with both additive faults and loss of effectiveness faults is considered.…”

“…The work in [23] presented a novel cooperative fault-tolerant fuzzy control scheme for multi-agent systems with the actuator bias faults. In [24], the authors proposed a decentralized fault-tolerant synchronization strategy for a group of networked satellites with actuator faults. The work in [25] provided the performance analysis of a team of unmanned vehicles subject to actuator faults.…”

“…The control protocol of agents will be reconfigured after an actuator fault is detected. Although the authors in [23], [24] also discussed the active fault-tolerant methods, they only discussed the cooperative control problem with bias-type actuator faults. We consider the cooperative control problem with the bias-type actuator faults and the partial loss of actuator effectiveness.…”

Decentralized sliding-mode control for spacecraft attitude synchronization under actuator failures

“…Compared to Ref. [24] and [25], angular accelerations are avoided in the control laws in this paper.…”

“…In [24], distributed adaptive fault tolerant attitude coordination control laws are presented by the use of modified Rodriguez parameters for attitude representation. Fault tolerant terminal sliding mode controller is studied based on adaptive fuzzy approximation in [25] for attitude synchronization and tracking problem. However, angular accelerations are required in both approaches.…”
