Diseño de una estrategia de control robusto para manejo de temperatura a partir del modelo de un invernadero

Abstract

Greenhouse agriculture is part of a solution to climate management for plants through crop protection; however, agriculture indoor production systems present dynamics with nonlinearities, model uncertainties, and disturbances. The above generates unfavorable ecological conditions and low uniformity for environmental variables. Due to these premises, the current project sets out to design a control strategy to manage climatic variables such as temperature using robust techniques using a dynamic greenhouse model with specific characteristics extracted from the bibliography. The project has the following stages: recognition and implementation of the dynamic model to be used; simulation of the greenhouse model through software; design of a control strategy for the greenhouse using the algorithms: "Robust Regulator for Discrete-time Markov Jump Linear systems" in comparison with the "robust Linear Quadratic Regulator "; and finally the interpretation and analysis of the results to validate the most appropriate strategy based on the robustness of the controller, the simulation is performed in Matlab, through the use of an existing greenhouse model, studied and extracted from the bibliography, the project hopes to obtain the control strategy that achieves the desired adjustments.
