Virtual Environments to Fuzzy Control Applied to Nonlinear Autoclave Reactor

Abstract

This paper presents the design and implementation of a control algorithm based on fuzzy logic oriented to the area of teaching–learning processes in the chemical industry, more specifically of a nonlinear autoclave reactor. In order to evaluate the dynamic behavior against fuzzy control, an integration of software (MATLAB and Unity 3D) was developed, connected through DLL shared memories. The first software houses the fuzzy logic controller based on fuzzy sets and previously established linguistic variables; on the other hand, Unity 3D houses the dynamic model of the autoclave in order to simulate its real behavior. The latter software allows a more realistic conception of the chosen process, which is why we chose to design an immersive and interactive virtual environment with the virtual implementation of different elements of industrial instrumentation such as transmitters, valves, signaling, etc., animation of valves, control panels and a SCADA system.
