Adaptive cooperation in robust distributed model predictive control

Abstract

In this paper a new, adaptive cooperative form of robust distributed model predictive control is introduced. In the new algorithm, for linear, dynamically-decoupled subsystems in the presence of bounded disturbances, an optimizing subsystem determines the existence of paths in a graph representing currently-active coupling constraints. Where such paths exists, cooperation is promoted by the local agent designing a hypothetical plan for other subsystems. Robust feasibility and stability are maintained by permitting only non-coupled agents to update at each time step. By simulation, performance is shown to surpass that of using cooperation between immediately-adjacent agents, rivalling that of a dasiafully cooperativepsila implementation.
