Simple tuning rules for Feedforward compensators
In a recent study, simple tuning rules for feedforward compensators were applied to design a control strategy to regulate the inside air temperature of a greenhouse during daytime by means of a natural ventilation system. The developed control strategy is based on a PI (Proportional-Integral) controller…

Ventilation is also important for maintaining CO2 levels and removing excess moisture when there are no active systems installed to manage those factors. Ventilation…
Why cooling is an important part of climate control
Why is cooling important? Well, first to control temperature and humidity, secondly to avoid plant stress, then also to prevent over-irrigation and to ensure flower set. The selection…
