Network Layer Control System: Consensus-Based Control, Theoretical Results and Performance Issues
Sabato Manfredi · Advances in industrial control · 2016
In this chapter we formulate consensus-based algorithms operating at the network layer of the multilayer control system in Fig. 1.2 . We first define the concept of bottleneck switches/router cooperation and then present a network queue fluid model of the heterogeneous sources accessing to multi-bottleneck network. Finally we formulate a consensus-based cooperative control law that: (i) stabilizes the network; (ii) balances the queue length at a specified set point value \(q_0\) , reducing packet loss and improving link utilization; (iii) guarantees max–min fair allocation. The control algorithm can be implemented by end-to-end and hop-by-hop communication mechanism respectively over wired and wireless networks. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
