Enhanced Antenna Positioning Control System Using Adapted DC Servo Motor and Fuzzy-PI Controller

Abstract

Control systems for Ground Data Receiving Stations (GDRS) play a crucial role in accurately pointing antennas to receive data from satellites. This study focuses on designing and simulating a closed-loop control system using PID, LQR, and Fuzzy-PI controllers for precise antenna positioning and establishing reliable communication links during data receiving sessions. The proposed model incorporates a DC servo motor-based controller and antenna positioning system, implemented through MATLAB/SIMULINK software. Comparative analysis of the controllers is performed based on various performance metrics. The findings indicate that the Fuzzy-PI controller exhibits the most responsive and robust operation, outperforming the PID and LQR controllers. It effectively manages time delays in antenna control within the GDRS and supersedes the current controller with enhanced bypass, rise time, and tracking antenna calibration values. The study demonstrates the significance of optimizing control systems for ground stations, particularly when dealing with large motors, offering potential advancements in motor control and system stability. The proposed Fuzzy-PI controller presents a valuable solution for improving the overall efficiency of GDRS and enhancing its data reception capabilities.
