Dynamic Mechanistic Modeling of Air Temperature and Humidity in the Greenhouses with On-Off Actuators
Abstract: The mechanistic
models of greenhouse microclimate can be used as the simulators for designing new
control strategies. According to the on-off characteristics of the actuators in
greenhouse in China, the operating state of a greenhouse was divided into
several sub-states, and new mechanistic models of greenhouse air temperature
and humidity were built. In order to validate the new models, the relevant environmental
factors under three sub-states were measured in a glass greenhouse. The mean
square error of greenhouse air temperature and relative humidity are 0.57°C and
2.8% respectively. These results indicate that the new models are suitable for
the development of energy-saving control strategies of greenhouse microclimate
in future.
