Desenvolvimento de Torqueador Magnético para Controle de Atitude de CUBESAT Baseado na Teoria de Projeto Axiomático

Abstract

The article deals with the development of a magnetic torquer based on the axiomatic design theory to define the constructive characteristics of the device to be applied in the attitude control of small- size satellites. The physical principles of this actuator, the modeling of the characteristics to be manipulated by the theory, the proposal of a prototype and the initial experimental tests for the design strategy validation are presented. For the core of the coil that constitutes a torquer rod, an innovative material with nanocrystalline composition was chosen, the FINEMET®, aiming to take advantage of its magnetic permeability properties and reduced hysteresis phenomenon to generate a more linear signal, a requirement of the control system. Preliminary results show that the project proposal is promising as a contribution to the improvement of fundamental devices for the continuous and accelerated growth of the use of Cubesats.
