Impact of Decomposition on Distributed Model Predictive Control: A Process Network Case Study

Impact of Decomposition on Distributed Model Predictive Control: A Process Network Case Study
Prodromos Daoutidis, Ali Almansoori, Davood Babaei Pourkargar
This paper addresses the impact of decomposition on the closed-loop performance and computational efficiency of model predictive control (MPC) of nonlinear process networks. Distributed MPC structures with different communication strategies are designed for regulation of an integrated reactor–separator process. Different system decompositions are also considered, including decompositions into local controllers with minimum interactions obtained via community detection methods. The closed-loop performance and computational effort of the different MPC designs are analyzed. Through such a comprehensive comparison, tradeoffs between performance and computation effort, and the importance of systematic choice of the system decomposition, are documented.
