ABSTRACT
Overcoming the grip of the Earth's gravity has been a high-demand in current technology. Through work of engineers and scientist, human has found many ways to levitate a variety of objects to be applied in the field of mechanical and transportation.
Magnetic levitation (Maglev) is a way of using electromagnetic fields to levitate objects without any contact with other material. However, magnetic levitation system is unstable and non-linear. This paper presents the mathematical modeling of the magnetic levitation system. Since magnetic levitation system is a non-linear system, it is controlled using Proportional Integral Derivative (PID) controller and Fuzzy Logic controller. The PID, Fuzzy Logic and Fuzzy-PID control techniques will be simulated and compared to determine which one of them give the best control performance to the system.

ACKNOWLEDGEMENTS
First and foremost, I would like to express my appreciation to my project supervisor, Associate Professor Dr. Irraivan Elamvazuthi for his valuable input and guidance throughout the course of this project.
I would also like to express gratitude to Electrical and Electronics Engineering Department ofUniversiti Teknologi PETRONAS (UTP) for providing this chance to undertake this remarkable final year project.
Next, I would like to thank the Final Year Project (FYP) committee for arranging various seminars as support and knowledge to assist the students. Thanks to all lecturers and technicians from UTP especially Mr. Azhar Zainal Abidin who had provided untiring guidance and help throughout the period of the project.
Finally, I would like to apologize if any party was inadvertently excluded from being mentioned above and I would like to thank all parties that were involved in making this project a success. Thank you.
