SMALL SATELLITE ATTITUDE CONTROL AND SIMULATION
Keywords:
Satellite Attitude Control, Simulation, Mathematical ModelingAbstract
Different attitude control strategies of a small satellite are presented in this paper as well as their simulation with the MATIAB® software. Firstly, the linear mathematical model of the satellite is derived for the gravity gradient (GG) control method, which represents a passive control design. Simulation results show that the response of the satellite to initial conditions is marginally stable. The second phase of the study focuses on the design of a control algorithm used to damp the satellite oscillations around its equilibrium position with a simple hardware setting added to the satellite . The mathematical model of the new system is developed and simulation about the roll and yaw axis are realized. A consequent amelioration in the satellite response can be observed.
