Boundary control of a flexible aerial refueling hose system with dynamic event-triggered mechanism

In this study, a novel adaptive boundary control strategy with a dynamic event-triggered mechanism (dETM) is proposed for an aerial refueling hose system. The aerial refueling hose system is a typical distributed parameter system, which is modeled by partial differential equations, and a boundary controller is designed to suppress hose vibration based on this model. In the controller design process, the dynamic event triggering mechanism is introduced to reduce the frequent unnecessary signal transmission by the controller, thus minimizing actuator abrasion and improving the aerial refueling reliability. The stability of the closed-loop system is proved by the Lyapunov function method. Finally, numerical simulations are conducted to verify the effectiveness of the constructed control.
