Distributed control design for underwater vehicles [PDF]

, 2008
The vast majority of control applications are based on non-interacting decentralized control designs. Because of their single-loop structure, these controllers cannot suppress interactions of the system.

Distributed learning for multi-agent control of a dynamic system [PDF]

, 2011
This thesis describes an investigation of self-organising, distributed control of dynamic, non-linear systems. The distribution is achieved through a multi-agent based approach. The self-organisation is addressed through reinforcement learning.
