Multi-Path Alpha-Fair Resource Allocation at Scale in Distributed Software Defined Networks [PDF]

open access: yes, 2018
The performance of computer networks relies on how bandwidth is shared among different flows. Fair resource allocation is a challenging problem particularly when the flows evolve over time. To address this issue, bandwidth sharing techniques that quickly

Optimizing nonlinear adaptive control allocation [PDF]

open access: yesModeling, Identification and Control: A Norwegian Research Bulletin, 2005
A control-Lyapunov approach is used to develop an adaptive optimizing control allocation algorithm for over-actuated mechanical systems where the actuator model is affine in the uncertain parameters. Uniform global (asymptotic) stability is guaranteed by the control allocation defined by the dynamic update laws in combination with an exponentially ...
