Abstract
In this article, the predefined-time dual-channel event-triggered deployment control method is investigated for the space tethered system under communication resource constraints and external disturbances. A static event-triggered mechanism is designed for two channels, including the sensor-to-controller side and the controller-to-actuator side, thus reducing the communication burden of these two channels. Then, the event-triggered predefined-time backstepping controller is constructed based on these dual-channel event-triggered conditions, while a neural network is used to handle nonlinear function terms, and a transform function is designed to solve singular phenomena. Besides, Zeno behavior is avoided, and the stability of the closed-loop system is proved by the Lyapunov theory. Finally, the effectiveness of the proposed control scheme is exhibited by simulation tests.
