Abstract: A simple and efficient nonlinear controller on the Attitude Control System (ACS) onboard Earth Observation Satellites (EOS) is described. The control problems are mainly about the influence of the pointing stability from the disturbances and measurement noises, without considering the behavior of sensors and actuators. The performances of the nonlinear control system are checked by extensive simulations.
