Real Time Virtual Instrumentation based Control of Climatic Condition in a 4 x 2 MIMO Climatic Chamber through Expert System

Abstract

The comfort level of persons in living area, auditorium, patients in hospitals is ensured by -the climatic conditions of the zone. Climatic conditions also have an important impact in the areas such as food preservation unit, stock yards of perishable/non perishable goods. There is a big concern in maintaining the climatic conditions in horticulture for proper growth and yield of plants. The climatic condition[1] of a particular area is ensured mainly by controlling temperature and relative humidity. Today's world utilizes the advance control strategies for achieving a good control over temperature and relative humidity for establishing a environment with comfort climatic conditions. In this work a trail to control temperature and relative humidity is conducted inside an experimental multi input multi output  4 X 2 non linear climatic chamber by means of fuzzy logic controller. The fuzzy logic control system as an expert system is developed using virtual instrumentation software through which the performance of climatic chamber was investigated against disturbances introduced within the standard limits.
