ESTABLISHING TO CONFIGURATION AND MATHEMATICAL MODEL OF SYSTEM BY AUTOMATICALLY ADJUSTMENT FOR HUMIDITY AND AIRFLOW IN GREENHOUSES FOR VEGETABLES AND FLOWERS

Abstract

The paper proposes a scheme of automated control humidity and airflow greenhouses for vegetables or flowers. For the mathematical modeling of these parameters is considered a greenhouse cylindrical cone the air contains a lot of infinitesimal elements on which acts inlet and outlet pressures at a distance x along airflow ventilation. To construct the auto were passed equations of the time in Laplace, the initial conditions null knowing the transfer function, as well as the entry and exit of air, get representation system functional automatic adjustment of MIMO system . With these functions built in Simulink model to transfer control of the proposed system, but before it was examined stability of each transfer functions in MATLAB, observing that the system is fully observable and controllable.
