COMPARISON BETWEEN FUZZY LOGIC CONTROL AND PID CONTROL FOR THE CATALYTIC CRACKING PROCESS.

The goal of this work is to make an analysis of the performances of a fuzzy controller and a comparative study of fuzzy control algorithms versus a conventional control approach (Proportional Integration Derivative) in a case of the catalytic cracking process. The study is structured in four parts. The first part presents the process description and the classic control structure of the catalytic cracking process. The next two parts contain a detailed presentation of the fuzzy logic control structure for the proposed process and the development steps of the controller. In the last part of the paper, a performance analysis of the conventional PID controller and fuzzy logic controller has been done by the use of Matlab and Simulink and in the end a comparison of various time domain parameters has been performed in order to prove that the fuzzy logic controller has small overshoot and fast response as compared to the PID controller.
