In this paper a Model Predictive Method based controller is proposed to control a satellite. Model Predictive Control (MPC) has been well known as a practical control method for various systems in industry. A problem with this method is its computational effort and time consuming. To reduce computational load Laguerre functions have been proposed in this literature. Simulation results are given to show feasibility and the validity of the design. A comparison between the time consumed in the presence and the absence of the Laguerre functions is done too.

In this paper a robust controller using µ-synthesis method has been designed for attitude control system of a micro-satellite in LEO orbit. Then the controller has been evaluated with accurate linear and nonlinear simulations. After necessary evaluation three-axis stabilization method with only magnetic torques and auxiliary gravity gradient boom was been selected. Nonlinear kinematics and dynamics equation of this system was obtained and linearization was performed on it. Finally the system was converted into a multivariable linear time varying system and controller for this system was performed via µ-synthesis, which has been done by changing from time varying system into system with uncertainty.
