In this work, we deal with the identification of critical nodes in distributed control systems by means of game theoretical tools. This detection is addressed taking into consideration different factors such as the control performance under different topologies, the communication costs, and the centrality of the nodes in the network under study. In this sense, a generalization of the solution concept...
The evolution of distributed control techniques has led to the development of schemes where the communication burden is adapted dynamically: when the overall system is far from the control goal, the communication burden is augmented to improve the performance; when the system is close to its goal and there is no need of coordination, the distributed control scheme tends to behave as a decentralized...
We introduce a new method to perform the partitioning of non-centralized dynamical linear systems based on the relevance of the possible interconnections among the smallest components of the system. In particular, we analyze the importance of the interconnections using game theoretical tools, so that they can be arranged as a function of their expected contribution to the overall system performance...
In this paper, we deal with a distributed control scheme for linear systems in which the local controllers work cooperatively whenever the benefits from a control perspective are higher than the corresponding communication requirements. To this end, the network topology may vary with time so that all the communication links with a minor contribution to the overall performance are disconnected. Hence,...
We introduce several refinements in the design method of a coalitional control scheme for linear systems recently proposed. In this scheme, the network topology is modified in order to attain a trade-off between communication burden and overall system performance. In particular, all the communication links with low contribution to the overall performance are disconnected. Likewise, the control law...
We present a hierarchical distributed control scheme for large-scale systems in which the network topology is adjusted to fit to the dynamic coupling among the subsystems, considering the cost of data transmission. Each group of linked subsystems forms a coalition controlled by a closed-loop MPC scheme at the lower layer. The goal is to find a trade-off between the control performance and a reduced...
