Turn-Based Command Governor Strategies for Interconnected Dynamical Systems with Time-Varying Couplings

This work presents a novel distributed supervision architecture for reference signals management of dynamically coupled constrained linear systems where the dynamic interconnection among them can vary on-line to accomplish different operative scenarios. The strategy is based on non-iterative distributed command governor ideas that are here specialized to properly schedule modification on the couplings involving more than one subsystem. The main feature of the approach concerns the capability to avoid constraints violation regardless of any configuration change occurring on-line in the global plant/constraint structure. To this end, formal conditions to guarantee safe system configuration switchings are investigated by involving also graph colorability concepts. Simulation results on a water network are presented to illustrate the effectiveness of the proposed strategy.
