Magnetic Torquers Only Attitude Control of a 3U Cube Satellite

Abstract

In this paper, attitude control of a 3U CubeSat is discussed using magnetic torquers only. As the capabilities of attitude control systems increase, the use of magnetic torques in the CubeSat is becoming more popular. Attitude control using only magnetic torquers has been researched for years and is still a current problem to study. This paper presents the use of an LQR controller for a 3U CubeSat without full gravity gradient stability of the model in a deterministic approach.
