The Master’s thesis of the student Ghada Adnan Miteb, majoring in Control Engineering, was discussed on Thursday, 3/7/2024, at Hall No. 9 in the Department of Control and Systems Engineering. Her research was entitled: Intelligent Control of a Fluid Catalytic Cracking Unit in petroleum Refineries

The discussion committee consisted of:

1- Prof. Dr. Amjad Jalil Hamidi / Chairman.

2- Prof. Dr. Ammar Ibrahim Majeed / Member

The development of the oil industry, which is considered one of the most important economies in the world, is achieved through high product quality. Therefore, there is a need to control the most important units in petroleum refineries by controlling the temperature of the product, which is the fluid catalytic cracking unit (FCCU). In this work, the Firefly algorithm is used to find the best parameter values for the two types of controllers. The second controller design consists of two NPID controllers and two PDLT2 controllers. This design aims to compensate for disturbances and uncertainties in the FCCU. The reactor temperature overshoot in the simulation results is reduced by 90% and the regenerator temperature overrun is reduced by 85% compared to the results shown in Reference 20. The inherent coupling, uncertainty, chattering, and nonlinearity in the FCCU are handled by this type of controller. All results were obtained by MATLAB2020b. The discussion was attended by the Assistant Head of the Department for Scientific Affairs and Postgraduate Studies Prof. Dr. Abbas Hussein Issa. On this occasion, we congratulate the student Ghada Adnan Miteb and wish her continued success.
