Agriculture is an indispensable industry. Open field agriculture, however, requires large quantities of fertilizer, water, and land while representing a significant contribution to global greenhouse gas production. Moreover, open field agriculture is particularly sensitive to climate change as rising temperatures, floods, and droughts threaten food security in many areas of the world.
Controlled environment agriculture (CEA), such as greenhouse or vertical farming, offers a climate resilient alternative to open field agriculture with significantly lower fertilizer, water, and land use requirements. One of the main limitations of CEA, however, is that optimizing and maintaining climate conditions for plant growth is a complex and energy intensive task. While model-based and optimal control methods offer a potential solution, the large investment of time and expertise (i.e., cost) required to deploy these methods is prohibitive for applications such as CEA with many independent systems and high variability between systems.
This PhD project involves designing data-driven and modular control algorithms to address these challenges in CEA systems. These control algorithms should regulate the indoor temperature, humidity, CO2 concentration, and supplemental light input in CEA systems to maximize plant growth while minimizing energy cost and environmental impact. The goal is to leverage first-principles knowledge as well as advances in machine learning and data-driven control to design a control synthesis procedure specific to CEA applications. We plan to focus on modular approaches that allow us to apply the same low-cost control synthesis procedure to deploy controllers for a variety of CEA systems and plants with similar physics, but different parameters. During the project, we intend to collaborate with industrial partners and Wageningen University and Research (WUR) to test these algorithms on real CEA systems. By reducing the cost to deploy these advanced automation and control algorithms, we can expand the scope of these algorithms and thereby bring significant improvements to the resilience, economics, and sustainability of modern agriculture.

Challenge. Change. Impact!
From chip to ship. From machine to human being. From idea to solution. Driven by a deep-rooted desire to understand our environment and discover its underlying mechanisms, research and education at the 3mE faculty focusses on fundamental understanding, design, production including application and product improvement, materials, processes and (mechanical) systems.
3mE is a dynamic and innovative faculty with high-tech lab facilities and international reach. It’s a large faculty but also versatile, so we can often make unique connections by combining different disciplines. This is reflected in 3mE’s outstanding, state-of-the-art education, which trains students to become responsible and socially engaged engineers and scientists. We translate our knowledge and insights into solutions to societal issues, contributing to a sustainable society and to the development of prosperity and well-being. That is what unites us in pioneering research, inspiring education and (inter)national cooperation.
