| 中文摘要:针对虚假数据注入攻击下的直流微电网系统, 采用基于事件触发一致性理论和固定时间滑模控制方法对系统的母线电压控制展开研究。首先, 建立虚假数据注入攻击下的直流微电网系统模型。其次, 构造中间观测器和状态观测器, 分别估计虚假数据注入攻击和系统状态。然后, 提出一种设备运行模式自切换机制以改进分布式控制器设计, 同时引入事件触发一致性控制方法, 降低通信频次, 使各节点母线电压趋于一致。接着, 设计固定时间滑模控制器, 保证系统的稳定性。最后, 以直流微电网系统为例进行仿真, 仿真结果表明, 设计的控制方法能补偿虚假数据注入攻击产生的不良影响, 具有良好的鲁棒性, 而且能有效节约通信资源。 |

| Abstract:To solve the problem of DC microgrid system under false data injection attack, the bus voltage control of the system based on event-triggered consistency theory and fixed-time sliding mode control method was studied. Firstly, the DC microgrid system model under false data injection attack is established. Secondly, an intermediate observer and a state observer are constructed to estimate the false data injection attack and the system state, respectively. Then, a self-switching mechanism of equipment operation mode is proposed to improve the design of distributed controller, and an event-triggered consistency control method is introduced to reduce the communication frequency and make the bus voltage of each node tend to be consistent. Then, a fixed time sliding mode controller is designed to ensure the stability of the system. Finally, taking DC microgrid system as an example for simulation, the simulation results show that the designed control method can compensate for the adverse effects of false data injection attacks, with good robustness, and can effectively save communication resources. |
