Observer-based dynamic event-triggered H∞ LFC for power systems under actuator saturation and deception attack
作者：
Highlights：
• A unified dynamic driven and observer-based security LFC framework is established for power systems in which the time delays and actuator saturation are considered simultaneously. While, in many existing studies [24,35], only partly conditions were considered. Different from [25,36], the actuator saturation is also considered in this paper.
• A novel DETM is proposed by introducing the internal variable η(t) (t) and additional exponential term to reduce the pressure of data transmission. Compared with [17,23,41], we introduce an additional exponential term to further improve the communication bandwidth utilization.Moreover, the Zeno behavior is avoided naturally.
• The observer-based resilient control strategy and stochastic Lyapunov stability theory are developed such that the LFC systems are mean-square exponential stable. Finally, the simulations are given to prove the usefulness of the proposed method.
