Abstract

The invention discloses a temperature and humidity control algorithm for an intensive curing barn controller and relates to the technical field of environmental control in facility agriculture. Optimized PID (proportion integration differentiation) algorithm is used, and accurate control of temperature and humidity is realized by a controller. The controller comprises a PID controller, a relay link and a fuzzy controller for calibrating PID parameters; the PID controller completes control algorithm and calculates the control amount of output; initial parameters of the PID controller are achieved through the relay link; the fuzzy controller conducts online and real-time adjustments of the PID parameters of KP, Ki and KD according to deviation e and deviation rate of change ec so that the PID controller has adaptive capacity, and the system is always in an optimal control state. The temperature and humidity control algorithm for the intensive curing barn controller has the advantages of calculating parameters and variation amount of various environmental conditions in a curing barn, realizing accurate control of the temperature and humidity of the curing barn, and the like. Furthermore, the temperature and humidity control algorithm for the intensive curing barn controller can be used as a temperature and humidity controller in an intensive curing barn in domestic regions of any different latitude to conduct algorithm.

Description

technical field [0001] The invention relates to the technical field of environment control in facility agriculture, in particular to a temperature and humidity control algorithm for a dense barn controller. Background technique [0002] Tobacco leaf curing is the last important link that determines the quality of tobacco leaves. The quality of tobacco leaf curing is mainly restricted by the quality of fresh tobacco, baking equipment and baking technology. According to the requirements of tobacco leaf curing process, provide suitable environment such as temperature and humidity. Conditions are the key to ensure the quality of tobacco leaf curing. Before the popularization and application of intensive curing barns, the temperature and humidity in the barn were basically measured with a dry-humidity difference thermometer, and artificially controlled. This method is difficult to accurately implement the curing process, and it is difficult to guarantee the quality of tobacco lea...
