Plug-and-Play distributed model predictive control with coupling attenuation

Giancarlo Ferrari Trecate

We consider the control of a large-scale system composed of state-coupled linear subsystems that can be added or removed offline. In this paper we present Plug-and-Play (PnP) design methods based on Model Predictive Control (MPC) meaning that (i) the desig ...
