RESUMO

Increasing satellite autonomy is a continuing goal for improving its performance and reducing its operational costs. In this work, a new control algorithm based on fuzzy logic is presented, whose aim is to autonomously control a spin stabilized satellite with magnetic coils. Several simulations have been carried on to test the performance of the fuzzy logic controller under realistic conditions, such as: the occultation of the solar sensor during the orbital motion; and the use of a simple algorithm to determine the angular velocities of the body. In these simulations, the dynamic response of the fuzzy logic controller was observed and its performance was compared qualitatively and quantitatively with the conventional one. The First Brazilian Scientific Satellite - SACI1, under current development by the National Institute for Space Research INPE, is one of several possible missions that can take benefit from this approach. The simulations have shown that the fuzzy logic controller reached the control specifications established to the SACI1, leading the system to the nominal operational conditions, being at the same time simple and robust.
