The Temperature and Humidity Control of Artificial Climate Chamber Based on Feed-Forward Compensation Decoupling

Abstract

Artificial climate chamber is a kind of experimental and scientific equipment that can simulate the natural environment. Temperature and humidity are the main control parameters. At present, at home and abroad , most of temperature and humidity control algorithms of the artificial climate chamber belong to single factor control, they all ignoring the coupling problem between temperature and humidity. This process cannot ensure the accuracy of the system, and it is easy to cause system oscillation. Thus, in this paper, we use an algorithm called the feed-forward decoupling to eliminate the coupling between the temperature and humidity through the way of feed-forward compensation, finally we design the temperature and humidity fuzzy controller respectively as the single factor control.
