The master’s thesis of the graduate student Zainab Nima Mahmoud,

majoring in Mechatronics engineering, was discussed on Monday,

12/4/2023. The discussion was held at Hall No.9

in the Control and Systems Engineering Department.

Her thesis was entitled: Optimal Adaptive Control

for Drilling Machine in Composite Material

The discussion committee consisted of:

1- Prof. Dr. Safana Mudhir Raafat / Chairman.

2- Asst. Prof. Dr. Maher Yahya Salloom / Member.

3- Asst. Prof. Evan Esho Korial / Member.

4- Asst. Prof. Dr. Hudhayfah Khalil Ibrahim / Member and Supervisor.

5- Asst. Prof. Shaima Mahmoud Mahdi / Member and Supervisor.

Due to the diversity in physical and chemical properties of composite

materials, understanding the dynamics of the etching

process within these materials is challenging. One of the major concerns

that arise from lack of control over the drilling process is

the occurrence of distortions around the drill, which can significantly

reduce the quality of the product. To address this, the present study

proposes a proportional integral-differential (PID) ideal controller

and a model reference adaptive control (MRAC) system method.

To improve the performance of the proposed controllers,

the study proposes the Particle Swarm Optimization Algorithm (PSO)

and the Flower Pollination Algorithm (FPA), in addition to the

Enhanced Flower Pollination Algorithm (EFPA) based on the Integral

Time Absolute Error (ITAE). Simulation results in MATLAB

confirm the superior performance of the proposed EFPA in contrast

to the FPA and PSO methods to enhance the performance

of the proposed controllers. The MRAC controller also excelled

in controlling the drilling process under different operational conditions.

The results of this thesis provide effective approaches to enhancing

productivity and quality in productive companies. The discussion

was attended by the Assistant Head of the Department for Scientific

Affairs and Postgraduate Studies Asst. Prof. Dr. Abbas Hussein Issa.

On this occasion, we congratulate the student and wish her continued success.
