摘要

In the realm of space technology, robust ground systems are crucial for effective satellite communication. This study focuses on the design and analysis of dynamic controllers for satellite antenna tracking systems utilizing DC servo motors. Through the evaluation of three controllers LQR (Linear Quadratic Regulator), PID (Proportional-Integral-Derivative), and Fuzzy-PI. The research investigates their performance in optimizing antenna positioning within Ground Data Receiving Stations (GDRS). Utilizing mathematical modeling and simulation techniques, the study reveals compelling insights. Results indicate that the Fuzzy-PI controller surpasses PID and LQR counterparts, exhibiting superior responsiveness and robustness. Specifically, the PID controller demonstrated a very big slew rate and a very big overshoot Where, the LQR controller exhibited a big slew rate, and a minimal overshoot. Remarkably, the Fuzzy-PI controller showcased the lowest slew rate and a mere overshoot. These findings underscore the importance of meticulous control strategy selection to enhance system stability and efficiency in ground data reception operations. Moreover, the study provides practical implications for improving satellite data receipt and communication reliability, offering significant contributions to the field of space technology.
