This study is focused on the issue of $H_{\infty }$ antidisturbance event-triggered (ADET) control for aeroengine control systems (AECS) under multiple disturbances. First, a switched affine model is employed to describe the AECS, taking into account the degradation of aeroengine performance and the phenomenon of multimode operation. Second, a disturbance observer is established to compensate for disturbances that arise from the modeling error, uncertainties, and other factors. Then, based on the disturbance observer, a dynamic event-triggered mechanism with respect to the affine term and an $H_{\infty }$ ADET controller are built to optimize network transmission resources and fuel flow efficiency. Furthermore, a sufficient condition is developed to enable the solvability of the $H_{\infty }$ ADET control issue for AECSs. Finally, a simulation platform of hardware-in-the-loop for the AECS based on switched affine model is implemented to illustrate the effectiveness of the present $H_{\infty }$ ADET control methodology.
