Abstract: The distributed secure filtering issue of Takagi-Sugeno (T-S) fuzzy systems (TSFSs) under hybrid attacks is investigated in the framework of finite-time boundedness (FTB). The state is estimated via a wireless sensor network (WSN) in a distributed way, where each sensor collects information from the system independently, and transmits it to the remote local estimator through the measurement information transmission (MIT) network. The estimator interacts with others through the local information transmission (LIT) network. Firstly, to describe the dynamic changes of the system under hybrid cyber-attacks, a switched model with nine subsystems is introduced. Then, the conditions of the FTB of the filtering dynamic system are given by the switching system analysis method. Moreover, the quantitative relationship between the average dwell time of attack modes and the stability boundary is established. Finally, to demonstrate the efficiency of the designed filtering scheme, the simulation study on the tunnel diode circuits is provided.
