The inertia parameters information has an important role to ensure the success of the attitude control during satellite mission. However, in practical situations, the inertia of satellites can be changed due to the fuel consumption, the onboard motion and the rotation of solar arrays. And it is also difficult to be accurately determinated on ground because of the complexity of the satellite geometries. Therefore, it is important to develop a control strategies that take account the change of inertia parameters. This paper presents a controller design for microsatellite in the presence of inertia uncertainties based on adaptive backstepping technique. Firstly, the backstepping controller is developed when there are no uncertainties in the inertia matrix. After that, a controller is designed using adaptive backstepping technique to compensate the uncertainties of inertia and. The simulation results clearly demonstrate the effectiveness of the proposed technique.
