Comparative Study Between Fractional Linear Quadratic Regulator (Frac-LQR) and Sliding Mode Controller for the Stabilization the Three-Axis Attitude Control System of LEO Satellite Using Reaction Wheels
摘要
This paper presents a comparative study between two control strategies, namely Fractional Linear Quadratic Regulator (Frac-LQR) and Sliding Mode Controller (SMC), for the stabilization of the three-axis attitude control system of a Low Earth Orbit (LEO) Satellite using reaction wheels. The primary goal is to compare the performance of these controllers in terms of stability, robustness, and control effort in the presence of external disturbances and stabilization time. The control algorithms are implemented and analyzed through mathematical modeling and simulations through Matlab to validate their efficacy in maintaining the desired satellite orientation.
