Combining the energy and attitude control system is a feasible technology for small
satellites to improve the space missions. In this Combined Energy and Attitude Control System
(CEACS) a double rotating flywheel is used to replace the conventional battery for energy storage as
well as to control the attitude of an earth oriented satellite. Each flywheel is to be controlled in the
torque mode. The energy and attitude inputs for the flywheels' control architecture are also in the
torque mode. All related mathematical representation along with the relevant transfer functions and the
required numerical calculation are developed. The goals are to analyze the attitude performance with
respect to the ideal and non-ideal test cases for a chosen reference mission
