Abstract

Fuzzy logic in position control system was a project that implemented fuzzy logic controller to control the position of the antenna azimuth rather than using the conventional controller such as PO controller that normally used to control the position of the antenna azimuth. The objective of this project is to design a fuzzy logic for a position control system, to simulate the fuzzy logic that has been designed by using MATLAB software to get the output result and then to compare the fuzzy logic with a conventional PD controller in position control system. This project began with analysis of the- antenna azimuth block diagram to get the plant tra.nsfer function. Then the project was divided into two parts. First part is to design the PD controller to control the plant. Then the second part is to design the fuzzy logic controller to control the plant. The result that has been obtained by using the MATLAB software is analyzed and the comparison in performance is discussed in the final stage of this project. In the end of the project, the fuzzy logic was improved to be more flexible and have a better performance compare to the PO controller in control the position of the antenna azimuth.
