中文摘要: |
针对DoS(Denial-of-Service)攻击,分析了具有短时延的网络控制系统(networked control systems,NCS)的稳定性,设计了该系统的保性能控制器.首先,通过采样周期的重新定义,把该类NCS建模成离散切换系统模型,该模型可以把短时延和DoS攻击统一起来.接着,用离散切换系统的分析方法,给出了一个该类NCS指数稳定的充分条件.进一步,在给定的保性能水平下,设计了相应的保性能控制器.最后,通过一个仿真示例说明了结果的有效性. |
英文摘要: |
Aiming at Denial-of-Service (DoS) attacks, the stability of networked control systems (NCS) with short network-induced delays is analyzed, and guaranteed cost controller is designed. Firstly, the NCS is modeled as a discrete-time switched system model by redefining the sampling period. The model can unify the short network-induced delays and DoS attacks. Then, with the analysis method of the discrete-time switched systems, a sufficient condition is derived for the concerned NCS to be exponentially stable. Moreover, an optimal guaranteed cost controller is designed at a given guaranteed cost level. Finally, a simulation example is given to show the effectiveness of the result. |
