Abstract
This paper investigates the T–S fuzzy control of DC microgrids subject to false data injection (FDI) attacks, premise mismatching, and network delays using a dynamic event-triggered mechanism (ETM). Unlike the static ETMs using the fixed triggering parameters, by adaptively adjusting the triggering parameters, the proposed novel discrete-time dynamic ETM can more effectively reduce excessive usage of communication resources, and the Zeno behavior is also avoided naturally. Then, a novel T–S fuzzy closed-loop system model is built, which considers the FDI attacks, dynamic ETM, delays and premise mismatching all in one unified framework. Mean-square exponential stability criteria are derived, which establish the relationship between system performance and the contributing factors. Further, unlike the two-step emulation based method, the proposed co-design method can design the injection current controller and the dynamic ETM in one step, which offers a convenient framework for the tradeoffs between control and communication performances. Both simulation and experimental results confirm the effectiveness of the proposed methods, achieving 27.5% savings of communication resources while effectively stabilizing the DC microgrid even under the situation that 13.5% of the transmitted data are tampered by the FDI attacks.
