摘要

研究了具有假数据注入攻击和丢包的网络控制系统的非脆弱H∞控制器设计问题。采用非脆弱H∞控制器使系统对外界干扰或随机因素具有容忍度或不敏感度。首先,采用离散时间方法将被控系统转换为离散时间系统。随后,利用随机分析技术和总期望定律,导出了网络控制系统的稳定条件。然后,得到理想的非脆弱H∞控制器,该控制器使被控系统具有理想的H∞性能,并具有指数均方稳定。最后,通过数值仿真和飞机飞行控制系统验证了所设计方法的有效性和实用性。

Non-Fragile H∞ Controller Design for Networked Systems Under False Data Injection Attacks and Consecutive Packet Dropouts
In this paper, the non-fragile H∞ controller design problems for the networked control systems with false data injection attacks and packet losses are investigated. A non-fragile H∞ controller is utilized to render system tolerant or insensitive to external disturbances or random factors. First, the controlled system is converted into a discrete-time system by discrete-time approach. Subsequently, with the stochastic analysis technology and the law of total expectation, the stability condition of the networked control system is derived. Then, the desired non-fragile H∞ controller is obtained, with which the controlled system is exponentially mean-square stable with a desired H∞ performance. Finally, a numerical simulation and an aircraft flight control system are exploited to confirm the validity and practicability of the designed approach.
