| 摘 要： | 针对升力式再入飞行器的制导问题，首先利用准平衡滑翔原理给出标准的阻力加速度．速度剖面，并对阻力加速度跟踪制导原理进行分析，然后利用自回归小脑模型神经网络（RCMAC）网络良好的非线性逼近能力、泛化能力和自学习能力，采用基于RCMAC网络的动态逆方法实现对阻力加速度的跟踪，并证明闭环系统的稳定性．三自由度仿真结果表明，该制导方式降低了动态逆方法对模型的依赖，增强了制导系统的鲁棒性．

| Abstract: | Aimed at reentry guidance problem for lifting reentry vehicle,a dynamic inversion reentry guidance based on RCMAC is proposed.First,a nominal drag acceleration-velocity profile is given according to the quasi-equilibrium principle,and the drag acceleration tracking guidance method is analyzed.Then,taking advantage of the nonlinear approximation ability,generalization ability and self-learning ability,RCMAC network is integrated in the dynamic inversion method to track drag acceleration.In the end,stability ... |
