In the last decade, the interest of many companies to undertake missions aimed at space research has increased dramatically. Currently, the focus is more and more on the large family of miniaturized satellites. This paper aims to define the main components of a minisatellite. Additionally, the torques for attitude stabilization are evaluated. The implementation system identified herein consists of magnetorquers and three reaction wheels. The simulations carried out to assess their behavior were performed in a virtual environment using SIMSCAPE-MULTIBODY. Its use has made it possible to develop control systems for the satellite under study. Finally, an effective proportional-derivative (PD) feedback controller was chosen and tuned through numerical experiments.

Abstract
In the last decade, the interest of many companies to undertake missions aimed at space research has increased dramatically.

The simulations carried out to assess their behavior were performed in a virtual environment using SIMSCAPE-MULTIBODY.
