A discussion of challenges related to the modeling and control of greenhouse crop growth, this book presents state-of-the-art answers to those challenges. The authors model the subsystems involved in successful greenhouse control using different techniques and show how the models obtained can be exploited for simulation or control design; they suggest ideas for the development of physical and/or black-box models for this purpose. Strategies for the control of climate- and irrigation-related variables are brought forward. The uses of PID control and feedforward compensators, both widely used in commercial tools, are summarized. The benefits of advanced control techniques—event-based, robust, and predictive control, for example—are used to improve on the performance of those basic methods. A hierarchical control architecture is developed governed by a high-level multiobjective optimization approach rather than traditional constrained optimization and artificial intelligence techniques. Reference trajectories are found for diurnal and nocturnal temperatures (climate-related setpoints) and electrical conductivity (fertirrigation-related setpoints). The objectives are to maximize profit, fruit quality, and water-use efficiency, these being encouraged by current international rules. Illustrative practical results selected from those obtained in an industrial greenhouse during the last eight years are shown and described. The text of the book is complemented by the use of illustrations, tables and real examples which are helpful in understanding the material. Modeling and Control of Greenhouse Crop Growth will be of interest to industrial engineers, academic researchers and graduates from agricultural, chemical, and process-control backgrounds.

Modern greenhouse technology has revolutionized the food supply chain scenario over the past 40 years. Closed-field cultivation by means of agri-cubes, plant factories, vertical farming structures, and roof-top solar greenhouses has become the backbone of sustainable agriculture for producing all-year-round fresh fruits and vegetables. This book is an attempt to explore several profound questions such as how digital technology and simulation models have saved energy in commercial greenhouses, and why growers prefer LPWAN sensors and IoT monitoring devices over the traditional timer-based controllers? How artificial intelligence is capable of performing microclimate prediction and control, and what considerations should be taken into account for implementing desiccant evaporative cooling systems? With case-study examples and field experiments, each chapter highlights some of the most recent solutions and adaptation strategies toward improving the efficiency and sustainability of closed-field crop production systems.
