Abstract：To address the problem that nonlinear networked systems were often subjected to aperiodic denial-of-service attacks and false data injection attacks,the switching observer-based dynamic event-triggered control for a class of interval type-2 fuzzy networked systems was investigated.Firstly,considering the intermittent nature of aperiodic denial-of-service attacks and the unmeasurability of some system states,a nonlinear system based on the interval type-2 fuzzy model with switching observers was constructed.Meanwhile,to better save communication resources,a more advantageous dynamic event-triggered control method was employed.Subsequently,by applying the Lyapunov stability theory,a stochastic asymptotic stability condition for the controlled system and a controller design approach were derived.Finally,the stability of the controlled system when both types of network attacks occur was verified through a simulation example.This research provided key support for interval type-2 fuzzy systems to enhance their anti-interference capability and operational reliability when coping with hybrid network attacks,and possessed significant theoretical and practical application value.
