Abstract: An adaptive memory-event-triggered encryption control scheme is proposed for networked interval type-2 (IT2) Takagi-Sugeno (T-S) fuzzy control systems. First, the buffer is utilized to obtain the average value of the transmitted data. An adaptive threshold is established based on the relative error between the triggered data and the sampled data. The adaptive memory-event-triggered scheme (AMETS) is designed in the sensor-controller channel and the controller-actuator channel. Based on the AMETS, an improved Paillier encryption scheme is proposed, capable of encrypting and decrypting non-integer plaintexts while ensuring decryption accuracy. Then, a fuzzy dynamic output feedback controller is designed and an IT2 fuzzy closed-loop system is constructed. Furthermore, the controller gains and event triggering parameters are obtained by linear matrix inequality method to achieve the mean-square asymptotic stability of the system. Finally, the superiority of the proposed scheme is verified by simulation example. The scheme not only saves network resources and ensures the mean-square asymptotic stability of the system, but also reduces the loss of useful information and ensures the security of the data during transmission.
