Switched T-S Fuzzy Systems Control With Event-Triggering

Switched T-S fuzzy systems refer to switched systems in which each sub-system has the characteristics of T-S fuzzy systems.Since the nonlinear characteristics of complex and multi-mode physical systems in actual engineering can be accurately characterized,switched T-S fuzzy systems have extensive theoretical research and practical application value.In addition,in terms of reducing systems resources consumption,event-triggering schemes can trigger sampling and transmit according to the changes of the control system performance,thereby saving and scientifically configuring the transmission and computing resources of the control system under the premise of ensuring system performance.Research on event-triggering schemes and control problems have been widely used in many control fields.However,in the field of control research,the problems of event-triggered control for switched T-S fuzzy systems have not received enough attention.In view of this,this paper studies the analysis and control of switched T-S fuzzy systems based on event-triggering schemes.Firstly,this paper applies discrete event-triggering schemes to switched linear systems and analyzes its dissipative performance.This lays a theoretical and methodological foundation for the study of the full-text topic “Event-triggered control of switched T-S fuzzy systems”.Secondly,for the system fault detection problem,consider the data disorder phenomenon caused by the large delay in the network transmission process and the impact of malicious cyber attacks,an active packet loss method is adopted and event-triggered fault detection filtering problem for switched T-S fuzzy systems is studied.Furthermore,consider that the switching signal can also be sampled and triggered as a communication signal,which cause asynchronous switching.At the same time,the system control channel is threatened by data injection attacks.The problem of adaptive event-triggered asynchronous control for switched T-S fuzzy systems subject to cyber attacks is studied.Finally,according to the physical characteristics of the system,the decentralized control problem for switched T-S fuzzy systems is studied.The adaptive sampling communication schemes are designed,and the corresponding event-triggering schemes are adopted for multiple decentralized channels,which make the control system design more flexible and practical.The results obtained in this paper have been validated by numerical simulations.
