Modeling of greenhouse energy modes

The issues of increasing energy efficiency and improving the quality of automatic control of air temperature in industrial greenhouses are considered. The aim of the conducted research is to improve the energy efficiency of aboveground heating systems for industrial greenhouses by improving the known linear methods of automatic control by deviation and disturbance due to additional use of short-term meteorological forecast data on the upcoming change in outdoor air temperature. To solve the problem of transport lag in the control object when generating a control signal in the disturbance compensation circuit, in addition to the signal from the outdoor temperature sensor, the data of the forecast of changes in outdoor temperature, illumination and wind speed for a certain upcoming time interval are also taken into account, which allows for an appropriate compensating control action in advance. The proposed control method can be used to regulate air temperature in buildings and constructions with higher requirements for microclimate parameters.
