提出了一种再入机动飞行器（maneuvering reentry vehicle,MRV）的最优制导与控制方案。针对MRV再入机动轨迹优化问题,提出了新的基于Gauss伪谱优化方法的分段优化策略;由产生的最优参考轨迹,生成系统的外环最优制导指令。接着利用轨迹线性化控制（trajectory linearization control,TLC）方法设计系统的内环控制律。基于MRV完整的非线性六自由度模型,仿真表明提出的再入轨迹优化设计方法是有效的,而且内环TLC控制器可以准确地跟踪外环的最优制导指令和最优轨迹,并对系统未建模特性和参数不确定性具有一定的鲁棒性能。

英文摘要：

An optimal guidance and control architecture for a maneuvering reentry vehicle（MRV） is proposed.Based on the Gauss pseudospectrum method,a new multi-phases optimization strategy is proposed to deal with the difficulties in the optimization of maneuvering trajectory for MRV.Out-loop optimal guidance commands are generated from the resulted optimal reference trajectory.The inner-loop control law is designed based on the trajectory linearization control（TLC） method.Using the full nonlinear six degree-of-freedom model of the MRV,the simulation results show that the trajectory optimization method is effective,and the TLC controller of the inner-loop is able to track the maneuver command and the optimized trajectory accurately and robustly in the presence of unmodeled dynamics and parametric uncertainties.
