拒绝服务攻击下直流微电网的事件触发控制

本文研究受拒绝服务攻击下直流微电网的事件触发控制问题. 考虑到直流微电网的状态并不总是可获得, 设计了一个观测器来估计直流微电网的状态. 基于观测器的估计状态, 对于受拒绝服务攻击的直流微电网设计了一种新颖的弹性攻击的事件触发控制器. 所提出的控制器设计方法可以通过分离方法转化成一个凸问题. 此外, 在所设计的事件触发机制中, Zeno行为也被讨论并且通过矛盾法被排除. 最后, 一个实际的电网例子被用来验证所提出的控制方案的有效性.

Event-Triggered Control of DC Microgrids With DoS Attacks

This paper investigates the event-triggered control problem for direct-current (DC) microgrids with denial-of-service (DoS) attacks. Considering the fact that the states of DC microgrids cannot be always measurable, an observer is designed to estimate the states of DC microgrids. Based on observer states, a novel attack-resilient event-triggered controller is designed for DC microgrids under DoS attacks. The proposed controller design method can be converted into a convex problem by proposing an improved separation method. Besides, the Zeno behavior is also discussed and eliminated in the designed event-triggered mechanism by using the contradiction method. Finally, a practical microgrid example is shown to illustrate the effectiveness of the proposed control scheme.
