“…In many large‐scale networks, there is a significant concern that the actions of a control authority may make other regulation and control tasks difficult, or disrupt responses on remote input‐output channels. For instance, operators of the electric power grid have recognized that newly‐integrated fast controls may alter performance of other controls, or cause unexpected disturbance responses 20,22 . These concerns suggest that, while controllers are typically designed to achieve desirable internal properties, they may incidentally alter the input‐output characteristics of remote channels in undesirable ways (eg, cause the channel to become nonminimum phase, or increase susceptibility to disturbances).…”

“…[11][12][13] Particularly relevant to our effort here, graph-theoretic characterizations of the input-output structure of networks, as codified in the finite-and infinite-zeros of a channel transfer function, have been developed for diffusive network models. [14][15][16][17][18][19][20] Input-output properties have also been considered in the context of malicious control in the electric power grid, 21 and constrained resource optimization to curtail spreads in networks, 5 among other applications.…”

Control-channel interactions in a linear diffusive network model are studied, with the aim of determining the role of the network's topology in such interactions. Specifically, the influence of a built controller on the infinite and finite zero structure of a second control channel is characterized. The analysis shows how the network's graph topology, the relative positions of the two channels, and the architecture of the built controller influence the zero structure of the second control channel. Further, the influence of low or high gain controller designs on remote channels is examined. The analyses demonstrate that some control architectures and positions can introduce undesirable nonminimum-phase dynamics at remote locations, while others are guaranteed to maintain or promote minimum-phase dynamics.
