| Abstract |
The temperature and humidity inside poultry houses are highly coupled through nonlinear
psychrometric processes, and the limitation of actuators makes this type of system difficult to
control. To understand the dynamics of such systems and further to design a suitable controller,
in this study, the mathematical model for a closed poultry house was derived from the
governing equations of the various components related to the poultry house, including the
energy and mass balance and the psychrometric correlations of the moist air. The model was
simulated and the simulation result was compared to the data collected experimentally for
model verification and control gains estimation. Under the assumptions of 70 percent Active
Mixing Volume (AMV) with the constant maximum ventilation rate in the case study, the
temperature and the relative humidity simulated results were in the good agreement with the
real physical plant data. At the front, the middle and the rear part of the poultry house, the root-
mean-square error (RMSE) obtained for internal temperatures are 1.17o
C, 0.68o
C, and 0.46o
C,
respectively. And those data for relative humidity are 4.31%, 8.07%, and 53.54%, respectively. |
