This paper investigates the ISS problem for T-S fuzzy systems with multiple transmission channels under DoS attacks, proposing a time-triggered data update logic and a switched fuzzy dynamic output feedback controller. A novel time division mechanism is introduced to handle uncertainties caused by DoS attacks at different time periods, ensuring the ISS of T-S fuzzy systems under DoS attacks.
This paper investigates the input-to-state stabilizing (ISS) problem for Takagi?Sugeno (T?S) fuzzy systems with multiple transmission channels under denial-of-service (DoS) attacks. To achieve ISS, timetriggered data update logics on different channels are determined by linear matrix inequalities (LMIs). Under DoS attacks, a switched fuzzy dynamic output feedback controller which takes the security of premise variables into consideration is constructed. A novel time division mechanism is proposed to deal with the uncertainties caused by DoS attacks at different time periods. The proposed mechanism considers all cases of DoS attacks, which is more general compared to the existing method. Then, sufficient conditions are given to ensure the ISS of T?S fuzzy systems under DoS attacks. Finally, two examples are given to illustrate the effectiveness and merits of the proposed method. ? 2021 The Franklin Institute. Published by Elsevier Ltd. All rights reserved.
