| 摘 要： | 针对可重复使用运载器(RLV)再入初始阶段反作用控制系统(RCS)姿态控制问题,提出了混合整数线性规划(MILP)实现RCS喷流控制策略,并应用反馈线性化理论实现RLV再入六自由度非线性模型的线性化,设计了PID控制器,并完成典型制导指令跟踪仿真.仿真结果验证了MILP控制策略的有效性.

| Abstract: | This paper proposes a mixed integer linear programming(MILP) formulation of the RCS problem that is designed to control the RCS control allocation problem for the RLV re-entry in an exoatmospheric flight phase.By combining the PID with feedback linearization(FBL) it is possible to use linear,traditional algorithms with nonlinear models,and finish the simulation for verifying the effectiveness of the MILP control strategy. |
