Output regulation problem for a decentralized networked control system under jamming attacks and actuator saturation is solved by state feedback in this paper. A jammer's power allocation strategy aiming at degrading signal-interference-plus-noise ratios and leading to packets dropout in different wireless transmission channels of the decentralized networked control system is derived. In the presence of attack-induced packets dropout, a relation between null controllable region and regulatable region is described. For a plant and an exosystem, an asymptotically regulatable region is constructed based on a null controllable region. At last, an illustrative example certificates effectiveness of the presented techniques.
本文通过状态反馈解决了受干扰攻击和执行器饱和影响的分散网络化控制系统的输出调节问题。推导了一种干扰器的功率分配策略,该策略旨在降低分散网络化控制系统不同无线传输信道中的信号干扰加噪声比并导致数据包丢失。在存在攻击引起的数据包丢失的情况下,描述了零可控区域和可调节区域之间的关系。对于一个被控对象和一个外系统,基于零可控区域构造了一个渐近可调节区域。最后,一个示例验证了所提出技术的有效性。
