Book excerpt: This publication emphasises that an interdisciplinary and multi-disciplinary cooperation of scientists throughout the world is important in solving the complex problems facing the greenhouse industry. The book itself is an outstanding example of such cooperation.The aim of the book is to describe and analyse crop production in greenhouses in relation to climate control, to redefine the problem of (optimal) control from a theoretical point of view, and to provide a suitable framework for the design of new, scientifically based control systems. Though the principles are generally applicable, they are discussed against the background of the Dutch greenhouse industry. To provide the reader with some background information, the historical developments and the economic position of the Dutch horticultural industry are briefly reviewed in the introductory chapter. ...this book will certainly become a reference as such an extensive review on the greenhouse-crop system and its control is lacking for research and teaching...

Download or read book Modeling and Control of Greenhouse Crop Growth written by Francisco Rodríguez and published by Springer. This book was released on 2014-11-01 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Greenhouse Horticulture written by Cecilia Stanghellini and published by Brill Wageningen Academic. This book was released on 2024 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an integrated approach to crop growth and development and the technical aspects of greenhouse cultivation and climate management. It combines an analysis of the relationship between crop production and ambient climate with an explanation of the processes that determine the climate in a protected environment. With the ability to modify the environment comes the need for growers to strike a balance between the costs and benefits of technology. This book outlines the methods and gives several examples of how to make 'optimal' choices about technology. Sustainable management of shoot and root environment is discussed, as well as the pros and cons of vertical farming. The processes addressed in this book, like crop growth, energy balance and mass exchange, apply to any kind of greenhouse. Therefore, in spite of the word 'technology', this is not a book about high-tech greenhouses only. 'Greenhouse horticulture' is an easy-to-read textbook for all those interested in protected cultivation, from university students and teachers to professional advisers in the field and managers of horticultural companies.

Download or read book Integrated Greenhouse Systems for Mild Climates written by Christian von Zabeltitz and published by Springer Science & Business Media. This book was released on 2010-10-01 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crop production in greenhouses is a growing industry, especially in mild climates, and is very important for the population as a source of income and clean, fresh food. Greenhouses create optimal climate conditions for crop growth and protect crops from outside pests. At the same time greenhouse production increases water use efficiency and makes integrated production and protection (IPP) possible. This book provides technical instructions for practice (what to do and what not to do) and gives answers to the question: How to produce more clean crops and better quality with less water, less land and less pesticide. Suitable greenhouse constructions and their design, adapted to local climates in subtropical, tropical and arid regions and infrastructure conditions are presented. The necessary climate control measures - light transmittance, ventilation, cooling, heating, and CO2 enrichment - and physical measures for pest control, as well as methods for using solar energy to desalinate salty water are described. The results of theoretical research are transferred into methods for practical use, so that readers are equipped to solve their problems in practice as well as to get stimulation for further research and development.
Download or read book Multi objective Evolutionary Optimization in Greenhouse Control for Improved Crop Yield and Energy Tradeoffs written by Jose R. Llera Ortiz and published by . This book was released on 2020 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: The worldwide increase in demand for fresh fruits and vegetables has led to a search for strategies to manage greenhouses in ways that not only meet this demand, but that are also economically viable and environmentally sustainable. A well-established approach for managing greenhouse microclimate is through the automatic control of its mechanical systems such as heaters, ventilators, and shade screens. Such a system is a form of closed-loop control, but only with respect to the greenhouse microclimate, rather than the crop being grown. In practice, conventional greenhouse control is criticized for this focus on climate control instead of crop production, as well as the complexity of managing these systems due to an excessive number of user settings [1]. A more comprehensive form of closed-loop optimal control in greenhouses has been proposed to provide a better degree of control by adjusting the greenhouse climate in response to the growth of the crop being cultivated, but it is still dependent on the external climate around the greenhouse and can lack acceptable alternatives due to the nonlinear nature of the interactions between environmental conditions and plant growth. Unfortunately, monitoring of the real-time response of the crop is not viable for this type of closed-loop control - what can be used instead is a rather sophisticated state model of crop production so that the microclimate conditions can be controlled in order to optimize their effects on the predicted seasonal crop production. Further, this model and the greenhouse microclimate model into which it is integrated must be executable in a short enough timeframe to allow running it thousands of times to optimize the performance of the controller for a given greenhouse structure and location. Having developed such a model, we propose using a form of evolutionary multi-objective optimization to discover a suite of user-selectable control strategies that balance crop productivity with the financial costs of greenhouse climate control. Each of the Pareto-optimal controllers discovered by this approach defines a range of conditions to be maintained via specified control actions, depending upon the crop state and external environmental conditions. Due to the large number of candidates present as the output, the decision-making process will be aided by considering common user preferences as well as algorithmically examining the robustness of solutions in the final Pareto-optimal frontier.
