Decentralized event‐triggered robust MPC for large‐scale networked Lipchitz non‐linear control systems

Abstract This article examines a decentralized event‐triggered robust model predictive control (MPC) for a class of networked large‐scale non‐linear Lipchitz systems. It is assumed that the subsystems are geographically distributed and the connections can be made over a communication network and the...
