Research on Guidance under Multiple Constraints for Near Space Vehicles
The guidance and control for near space vehicles are subjected to multiple constraints. To actualize the goals of guidance and achieve the flight mission, a guidance method for near space vehicles under the consideration of multiple constraints is proposed in this paper. The guidance problem is decomposed into two subproblems, a trajectory planning subproblem and a trajectory tracking subproblem. Based on the parameterized modeling to angle of attack and the optimizing process of these parameters, the optimized longitudinal reference trajectory with the longest range is obtained. Then, a tracking law is designed to follow this longitudinal reference trajectory, and the robustness is reinforced via the double-loops structure of the tracking system. Finally, the guidance method is demonstrated by simulation, and the detailed analyses are given at the end of this paper.
