探讨了通过本地外部驱动或反馈控制的网络化的cyberphysical设备的操纵，在一个典型的多智能体动力系统的背景下，从事共识或同步任务。一个主要的焦点是了解利益相关者是否可以通过劫持一个代理的驱动信号来操纵整个网络的动态，以及有多容易。显式的频谱特性给出的能量（努力）所需的动力学操纵。这些特征用于（1）获得易于操作的结构见解，（2）显示沿着共识流形的操作沿着是容易的，以及（3）解决网络设计以启用或防止操纵。此外，它表明，多智能体系统可以有效地操纵沿着共识流形使用本地反馈控制，这不需要模型知识或广域测量。
The manipulation of networked cyberphysical devices via local external actuation or feedback control is explored, in the context of a canonical multiagent dynamical system that is engaged in a consensus or synchronization task. One main focus is to understand whether or not, and how easily, a stakeholder can manipulate the full network's dynamics by hijacking only one agent's actuation signal. Explicit spectral characterizations are given of the energy (effort) required to manipulate the dynamics. These characterizations are used to (1) gain structural insights into ease of manipulation, (2) show that manipulation along the consensus manifold is easy, and (3) address network design to enable or prevent manipulation. Additionally, it is shown that the multiagent system can be manipulated effectively along the consensus manifold using local feedback controls, which do not require model knowledge or wide‐area measurements.
