Abstract:

This paper proposes a new distributed control strategy for physically interconnected systems that adapts its communication structure at runtime to the current situation of the subsystems. The subsystems are permanently controlled by a decentralized feedback. Additionally, the local control units compute control inputs to other subsystems. To reduce the load of the network, control inputs are only transmitted to other local control units, while they are above given thresholds. Thus, the communication structure is adjusted to the currently acting disturbances. It is proven that the networked controller leads to a practically stable closed-loop system and that the deviation of its behavior to the behavior of a centralized control system can be bounded by an appropriate choice of the thresholds for the communication activation. Furthermore, a condition for designing the thresholds for the communication activation to guarantee a desired performance is given. The approach is demonstrated by its application to a thermofluid process.
