区间二型模糊网络系统的自适应记忆事件触发加密控制
Adaptive Memory-event-triggered Encryption Control for Networked Interval Type-2 Fuzzy Systems
摘要
Abstract
An adaptive memory-event-triggered encryption control scheme is proposed for networked in-terval type-2(IT2)Takagi-Sugeno(T-S)fuzzy control systems.First,the buffer is utilized to ob-tain 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-trig-gered 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 ine-quality method to achieve the mean-square asymptotic stability of the system.Finally,the superi-ority 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.关键词
