The application discloses a satellite model predictive control method based on convex mixed integer programming and belongs to the technical field of spacecraft orbit optimization and control, and solves the problems that traditional methods depend on continuous control input, are inconsistent with discrete characteristics of a satellite propulsion system, do not fully consider the discrete nature of a thruster, are difficult to consider accuracy and efficiency when dealing with complex maneuvers, and cannot effectively optimize fuel consumption. The application first establishes a non-convex optimal control model of a mission satellite, then convexes non-convex terms and introduces integer decision variables, then solves a benchmark trajectory of a convex optimization problem without collision avoidance constraints, finally solves a convex optimization problem with collision avoidance constraints to obtain an optimal control sequence, and realizes fuel optimization and collision avoidance. The application can uniformly deal with discrete switch decision of a satellite thruster and continuous trajectory optimization. The application can realize fuel optimization, reduce cost, accurately control the thruster and improve orbit adjustment accuracy.
