Abstract

Satellite attitude control is carried out to reach the target attitude as well as overcome various disturbances that cause the satellite's orientation or attitude to be kept off target attitude. The satellite control efforts are provided by the actuators, and the reaction wheel is one of them. The basic step to designing attitude control of a satellite is by understanding its dynamics. This paper reports the axisymmetric satellite behavior through simulation in MATLAB/Simulink. Some scenarios are carried out using simulations to explore the relationship between the satellite's motion behavior and its initial rotation without and with the reaction wheel. The simulations that run illustrate the relationships between the initial angular velocity of the satellite and the angular momentum of the reaction wheel, as well as at which axis (in relation to the moment of inertia) the reaction wheel is located. In addition, a comparison of simulation results using some different numerical solver settings was presented in statistical measurements, i.e., mean, median, and range of the magnitude of the satellite's angular velocity as well as the sample size. These facts show us that one may need to be more careful in choosing a numerical solver setting for simulating the dynamics of the satellites.
