A fixed-time fuzzy control framework for spacecraft based on disturbance estimator and guaranteed performance

This paper studies spacecraft attitude tracking issue under actuator faults and external disturbances. A dynamic estimator reconstructs the lumped disturbance without differentiating the measured attitude-rate signal. The estimation error decays exponentially for constant disturb...

Adaptive Preview Fault‐Tolerant Control With Partial‐State Feedback for Autonomous Recovery of UAV–UGV Collaborative Grazing

ABSTRACT The collaboration between UAV and UGV will greatly liberate manpower and improve the production efficiency of animal husbandry. The autonomous recovery of UAV is important for the whole collaboration system, especially when it meets with unexpected UAV faults and wind tu...
