The use of four reaction wheels to control the three-axis attitude of the spacecraft, considering its mechanical performance and the possibility of its failure, is a practical solution in the face of a defect in one of the wheels. In this article, the optimal control of the spacecraft, which has four reaction wheels, is investigated. Controlling the attitude of a spacecraft with just two reaction wheels is a significant issue that conventional controllers are not able to do. Therefore, the use of nonlinear model-based predictive controller is used to control the attitude of this spacecraft and compared with optimal nonlinear control in a discrete-time comparison, which satisfies the acceptable results.
