| 摘 要： | 将再入弹道跟踪问题转化为再入弹道状态调节问题,得到了一个LTV系统最优控制问题,在此基础上,利用基于伪谱算法的最优反馈控制算法,设计了一种便于在线实现的自适应鲁棒再入制导律.仿真结果表明该制导律在改变参考轨迹后依然能够较好地跟踪新的参考弹道,具备较好的动态性能和再入制导精度,而且不需要显示积分和显示增益调度.

| Abstract: | The trajectory tracking problem was transformed into a trajectory state regulation problem which is a linear time varying(LTV) system.An adaptive reentry onboard guidance law based on pseudo-spectral method was developed and simulated.Simulation results indicate that the reentry guidance law can track new reference trajectory with good dynamic performance and accuracy after the reference trajectory changed.One of the most important advantages is that the reentry guidance law can work well onboard without ex... |
