Such parallel systems are a fundamental system architecture frequently encountered in process networks where, in many cases, the state of the plant is not measurable. Economic performance is a key consideration in the operation of such industrial plants and it is of interest to develop theoretically rigorous approaches to tackle what is a practically very relevant scenario. The competitive couplings and competitive constraints inherent in parallel systems are explicitly addressed in the proposed controller design framework. Three measures are considered for optimization of such parallel systems including an economic stage cost function, energy efficiency and tracking accuracy. An economic cost function is optimized by the resulting distributed controller which can realize global control performance while also reducing the computational time for large-scale parallel systems. Stability of the system is formally proved using the principles of dissipativity. Finally, the effectiveness of the proposed theoretical approach is verified by both numerical simulation and experimentation to demonstrate practical relevance. date: 2024-09 date_type: published publisher: Oxford University Press (OUP) official_url: https://doi.org/10.1093/imamci/dnae025 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2304198 doi: 10.1093/imamci/dnae025 lyricists_name: Spurgeon, Sarah lyricists_id: SSPUR40 actors_name: Spurgeon, Sarah actors_id: SSPUR40 actors_role: owner full_text_status: public publication: IMA Journal of Mathematical Control and Information volume: 41 number: 3 pagerange: 564-589 issn: 0265-0754 citation: Zhang, Shuzhan; Li, Jia; Zhao, Dongya; Spurgeon, Sarah K; (2024) Output feedback distributed economic model predictive control for parallel system in process networks.
