Distributed Optimization With Event-triggered Communication via Input Feedforward Passivity
Mengmou Li, Lanlan Su, Tao Liu
In this work, we address the distributed optimization problem with event-triggered communication by the notion of input feedforward passivity (IFP). First, we analyze the distribut…
