FUZZY CONTROLLERS INSTEAD OF CLASSICAL PID CONTROLLERS IN HEATING, VENTILATION, AND AIR CONDITIONING SYSTEMS OF INDUSTRIAL PREMISES

Abstract

The article discusses the task of maintaining a stable temperature regime in production facilities, which is a key factor in ensuring the efficiency of technological processes, energy efficiency, and personnel safety. Traditional proportional-integral-derivative (PID) controllers are widely used to control the microclimate, but their effectiveness is limited by the inertia of the air environment, significant thermal loads on equipment, and changes in external conditions. The use of a fuzzy PID controller, which combines a classical control structure with a fuzzy logic apparatus, is proposed. A mathematical model of the thermal regime of the premises has been constructed, the architecture of the fuzzy PID controller has been developed, and modeling has been performed. A comparison with a classical PID controller showed a reduction in integral error indicators by 10-15%.
