Security control for T-S fuzzy systems with multi-sensor saturations and distributed event-triggered mechanism

摘要

This paper addresses security control for a class of Takagi-Sugeno (T-S) fuzzy systems with multi-sensor saturations and distributed event-triggered mechanism (DETM). As sensors can be located in different places, we will introduce a DETM to reduce the transmission rate of the network. The output measurements of each sensor are released into the network or not is dependent on the corresponding event-triggered condition. A new T-S fuzzy model is constructed, which characterizes the influences of multi-sensor saturations and cyber-attacks. Sufficient conditions are derived for ensuring the asymptotical stability of the augmented closed-loop system. The explicit expressions of the controller gains are obtained. Finally, the feasibility of the designed algorithm is shown by a numerical example. (c) 2020 The Franklin Institute. Published by Elsevier Ltd. All rights reserved.
