Intelligent satellites control based on fuzzy logic in the Earth-Moon Libration points

One of the most challenging issues in astrodynamic is the control of the satellites, in order to achieve a certain trajectory or to maintain some specific position with respect to a planet or to other spacecrafts. An interesting and quite innovative problem is the control of satellites around the five Lagrangian points of a binary system, using continuous thrust. In this work, using a complex and realistic model of the binary system, intelligent systems based on fuzzy logic are used to control the satellites in the Earth-Moon Libration points. The fuzzy controllers have been compared to conventional ones and it has been proved how this intelligent strategy reduces the control effort and therefore the fuel budget.
