Climatic control of a storage chamber using fuzzy logic

Abstract

Fuzzy logic has emerged as a superior control method for processes that are mathematically difficult to model. The paper investigates the potential of fuzzy logic for the control of a MIMO process with interactive process states. A fuzzy logic controller was designed and implemented for an industrial storage chamber where both temperature and humidity conditions are maintained during operation. Results from experiments and a comparison with PID control demonstrate the reliability and robustness of the controller under normal operating conditions and in the presence of disturbances.
