ABSTRACT: In this work, we simulate the proportional derivative (PD) control of the control system for the Attitude of the CubeSat U1 based on a set of 3 orthogonal magnetic torsion coils called Magneto-Torquer and analyze its functionality. The simulation of the PD control of the Attitude system is based on the Propat simulator programmed in MatLab, created by Dr. Valdemir Carrara. We obtain the data that will allow us to position the X face of the CubeSat U1, pointing towards Puebla city. The electromagnetic theory that allows us to generate the magnetic torque in the Magneto-Torquer is described as the variables that will be controlled in its application to control the CubeSat. We consider the radius of the Earth to be 6,371,000 meters. In particular, it is proposed to simulate with an orbit altitude equal to 300,000 meters with an eccentricity of 0.0002, with polar orbit, using a Magneto-Torquer to generate the movements necessary to locate the CubeSat, based on the simulation. For the simulation, the real conditions of outer space and the Earth’s magnetic field at the location of Puebla are considered, and the values for positioning the X face of the CubeSat towards this region are obtained. Confirm that simulation is a necessary and important tool for constructing systems used in Satellite technology, particularly in the Attitude system of a CubeSat. The development of aerospace technology has a fundamental tool in artificial satellites and nanosatellites, including CubeSats. This same tool is available for countries with limited economies to carry out aerospace projects by building their CubeSats. This work is important because it provides the basis for future work and even the start of a project that can be sent into outer space.
