Comparative study between Linear Quadratic Regulator and Fractional-Order robust controller for the ThreeAxis Attitude Control System of LEO satellite using reaction wheels

The attitude control system designates all the equipment and algorithms implemented autonomously on a spaceship. In satellites, the accuracy of the missions depends on the reliability and robustness of the controller it is one of the most important subsystems. The purpose of this paper is to design and apply a fractional-order controller specifically for the attitude stabilization of a Low Earth Orbit (LEO) satellite using reaction wheels. Real microsatellite parameters are used to test and run the fractional order controller, designed with MATLAB software which accurately stabilizes the attitude of the satellite system.
