abstract = "This work presents the attitude control system design procedures
for a three axis stabilized satellite in geostationary orbit,
which contains a flywheel suspended by two gimbals. The use of a
flywheel with two DOFs is an interesting option because with only
one device its possible to control the torques about vehicles
three axes; through the wheel speed control and gyrotorquing
phenomenon with two DOFs. If the wheel size and speed are
determined properly its possible to cancel cyclic torques using
gas jets only periodically to cancel secular disturbance torques.
The system, based on a flywheel, takes only one pitch/roll (earth)
sensor to maintain precise attitude, unlike mass expulsion based
control systems, which uses propellants continuously, beyond roll,
pitch and yaw sensors. It is considered the satellite is in
nominal orbit and, therefore, that the attitudes acquisition phase
has already elapsed. Control laws and system parameters are
determined in order to cancel the solar pressure radiation
disturbance torque and the torque due to misalignment of the
thrusters. Stability is analyzed and step and cyclic responses are
obtained.",
