Event-Triggered Adaptive Fuzzy Asymptotic Tracking Control for Rigid Spacecraft Attitude Systems With Full-State Constraints and Disturbances
Zhiguo Xu, Lin Zhao
Abstract
This article investigates the attitude tracking control of state constrained rigid spacecraft systems with external disturbances. An event-triggered adaptive fuzzy asymptotic backstepping tracking controller is proposed, which makes the spacecraft attitude tracking error asymptotically converge to origin in the presence of inertia uncertainty, external disturbance, and full-state constraints. A novel event-triggered mechanism is established to reduce the waste of communication resources caused by frequent controller updating. A simulation example demonstrates the effectiveness of the control method.
