Faster Response in Bounded-Update-Rate, Discrete-time Networks using Delayed Self-Reinforcement
For network control systems with fixed update rates, this work provides a method to significantly speed up response while maintaining stability.
The paper addresses the problem of slow response speed in bounded-update-rate discrete-time networks, and shows that delayed self-reinforcement (DSR) can improve settling time by over an order of magnitude without increasing update rate.
The response speed of a network impacts the efficacy of its actions to external stimuli. However, for a given bound on the update rate, the network-response speed is limited by the need to maintain stability. This work increases the network-response speed without having to increase the update rate by using delayed self-reinforcement (DSR), where each agent uses its already available information from the network to strengthen its individual update law. Example simulation results are presented that show more than an order of magnitude improvement in the response speed (quantified using the settling time) with the proposed DSR approach.
