Resumo
Greenhouses have a huge influence on agricultural industry, giving many benefits to rural producer like enable to cultivating seasonal cultures during all year, etc. and still having good value for money.In order to improve its efficiency and the quality of its products, thermal systems has been studied and improved instinctively in the last years.This development aims to study identification and modeling of thermal systems and project a PID controller, beside of that a desktop interface was produce to improve interaction between system and user, graphing in real time the temperature and the power consumed by the system, also saving data in text files for subsequent analysis.Least square method was utilized to model the process and a PID controller with derivative filter was elaborated using classic control methods.Presently the system already present the expected behavior, following the reference, staying stable and do not showing overshoot, fate that prove the efficiency of the math methods utilized in this project.
