| 摘 要： | 提出一种基于自适应补偿思想的再入飞行器纵向制导律改进方法.首先利用未知摄动函数描述纵向动力学方程,并基于此设计了对气动参数变化具有自适应能力的控制律,与原标准轨道控制律叠加形成全控制律,最终用于再入制导.仿真结果表明,所设计的控制律对于气动参数变化,大气密度变化具有较好补偿效果.

| Abstract: | Based on the standard ballistic, an improved longitudinal guidance law for reentry vehicle is proposed, which is deduced from compensation ideas. By using the unknown perturbation function, the longitudinal dynamics equation is described. Based on the equation, a guidance law is designed to adapt the changes of atmospheric parameters. The whole control contains the standard guidance law and adaptive compensation guidance law. The simulation results show that the designed control law can compensate the changes of aerodynamic parameters and atmospheric density. |
