Abstract

Satellite orbit transfer problems are treated using Feedback Linearization technique. The nonlinear dynamic system comprise of a spacecraft, which moves around the planet under the influence of Earth's gravitational field, whose dynamics is given by the two body problem. The trajectory is planned using optimal fuel transfer method, Hohmann Transfer. It gives the least speed change required for the coplanar transfer. Guidance law is designed using Feedback Linearization or Nonlinear Dynamic Inversion (NDI) technique, which transform a controllable nonlinear system into a linear form. The main objective is to plan the trajectory using Hohmann Transfer method and track it through Feedback Linearization technique.
