【摘要】 针对弹头再入直接力与气动面混合控制,对多喷嘴选择问题以及与气动面混合控制任务分配问题进行了研究,给出了基于模糊技术的多喷嘴选择的增量方案与混合控制的优化分配方法,并在此基础上设计了连续变增益滑模姿态控制器,最后进行了数值仿真。仿真结果表明在弹头再入过程中,滑模控制可以为期望角跟踪提供鲁棒、精确的控制方法,从仿真结果可以看出弹头在测试点由于舵效较低,直接力承担了主要的工作。这与实际情况相吻合,从而验证了方法的可行性。更多还原

【Abstract】 In this paper,aiming at the hybrid control problem of reaction-jet and aerodynamic surface of re-entry vehicle,the problems of hybrid control distribution and multi-nozzle selection are researched,and an increment scheme of multi-nozzle selection based on Fuzzy Logic and hybrid control distributing method is given,and a continious variational-gain scheme SMC controller is synthesized. In the end,the numerical simulation is done. Simulation results show that the aerodynamic surface takes on the main tasks during the re-entry process. The results of this paper can be applied to the full-physical simulation of re-entry vehicle.更多还原
