This article proposes an integral-based event-triggered attack-resilient control method for the aircraft-on-ground (AoG) synergistic turning system with uncertain tire cornering stiffness under stochastic deception attacks. First, a novel AoG synergistic turning model is established with synergistic reverse steering of the front and main wheels to decrease the steering angle of the AoG fuselage, thus reducing the steady-state error when it follows a path with some large curvature. Considering that the tire cornering stiffness of the front and main wheels vary during steering, a dynamical observer is designed to adaptively identify them and estimate the system state at the same time. Then, an integral-based event-triggered mechanism (I-ETM) is synthesized to reduce the transmission frequency at the observer-to-controller end, where stochastic deception attacks may occur at any time with a stochastic probability. Moreover, an attack-resilient controller is designed to guarantee that the closed-loop system is robust $\mathcal{L}_{2}$-stable under stochastic attacks and external disturbances. A co-design method is provided to get feasible solutions for the observer, controller, and I-ETM simultaneously. An optimization program is further presented to make a tradeoff between the robustness of the control scheme and the saving of communication resources. Finally, the low- and high-probability stochastic deception attacks are considered in the simulations. The results have illustrated that the AoG synergistic turning system with the proposed control method follows a path with some large curvature well under stochastic deception attacks. Furthermore, compared with the static event-triggered mechanisms, the proposed I-ETM has demonstrated its superiority in saving communication resources.
