Abstract: Abstract This study delves into an event-triggered hierarchical learning control framework for air-breathing hypersonic vehicles subject to practically constrained actuators. The hierarchical learning mechanism is adeptly integrated into both the control and allocation layers. In the control layer, an emotional deterministic learning control methodology is proposed with predefined-time disturbance observers and filters to attain predefined-time convergence of system tracking and learning, while compensating for lumped disturbances stemming from allocation errors and external disturbances. An intelligent triggered allocation approach is implemented in the allocation layer to distribute the desired control effect to the actuator with fast and low-complexity allocation considering practical actuator characteristics. The proposed control scheme ensures that all signals in the closed-loop system converge to a residual set in close proximity to the origin within a predefined time, whose time constant can be adjusted as desired by the designer. Furthermore, as the system is governed by the event-triggered mechanism, the communication burden can be considerably reduced. The effectiveness of the proposed controller is demonstrated through both theoretical proof and numerical simulations.
