On fuzzy control of ventilation process in air-ventilated closed areas with emission of noxious gases

Abstract

This paper presents the idea of the application of a fuzzy logic controller to the control of a ventilation process in air-ventilated closed areas with emission of noxious gases. The results of the simulation of such a control using an approximate model of the process mentioned above are shown. The experiment indicates that the delay time in the inflow of fresh air causes unfading oscillations of the concentration of gases, which may exceed the admissible level.<>
