In this research, a new method based on model-free adaptive control is used for the suboptimal guidance and control of a hypothetical three-stage satellite carrier in order to place the satellite in a predetermined orbit. So, first, a pre-designed nominal guidance is considered for the nominal model of the system. Then, by using this method, at the same time by correcting the direction to a small extent, both an instantaneous model for the system is estimated and a control policy is extracted. Correcting the guidance and determining the control policy is done by taking into account the passing of the practical assumptions governing the problem. The simulation results show the efficiency of this method, its stability and resistance to uncertainty in input and output changes for this class of control systems and objectives.The simulation results show the efficiency of this method, its stability and resistance to uncertainty in input and output changes for this class of control systems and objectives.
