Abstract
This paper researches the deployment control problem of the space triangular tethered satellite system under external disturbances and communication constraints from sensor to controller. An adaptive model-based event-triggered fuzzy sliding mode control scheme is proposed, making sure that the system is deployed to the specified configuration. The disturbance observer is used to estimate external disturbances, while the estimated model is constructed at the controller side to update control input without interruption under event-triggered mechanism. Then, the event-triggered fuzzy sliding mode controller based on the estimated model is designed, ensuring that the communication burden is greatly reduced and precise deployment control is achieved. Further, the stability of the closed-loop system is proved by the Lyapunov function based on the hybrid dynamical system. Eventually, the effectiveness of the proposed control scheme is tested by simulation tests.
