摘要:

为实现高超声速飞行器滑翔段时间协同再入,提出一种结合双参数插值侧倾角剖面和神经网络预测器的时间协同再入制导方法。首先,将高度-速度平面内的过程约束和终端约束转换为侧倾角走廊,并在其中构建基于双参数插值的侧倾角剖面以进行约束管理。其次,采用双层前馈神经网络实现航程与飞行时长的高精度实时预测,并通过求解双变量求根问题对剖面参数进行校正更新。在此基础上,结合航向角走廊横向制导与协同飞行时间确定方法,构建时间协同再入制导框架,实现制导指令的在线快速生成。最后,数值仿真结果表明,该算法能满足时间协同再入的各项约束,且制导精度高、适应性强;相比数值积分方法,神经网络仅需约10%的计算时间即可达到相近的预测精度;蒙特卡罗仿真表明,算法在初始状态与气动参数存在不确定性时,仍具备良好的鲁棒性。

Abstract:

To achieve time-coordinated reentry for hypersonic glide vehicles, a time-cooperative reentry guidance method based on dual-parameter interpolated bank angle profiles and neural network predictors is proposed. Firstly, the path constraints and terminal constraints in the height-velocity plane are transformed into bank angle corridors, and a bank angle profile based on dual-parameter interpolation is constructed within these corridors for constraint management. Secondly, a two-layer feedforward neural network is employed to achieve high-precision real-time predictions of the flight range-to-go and time-to-go, and the profile parameters are corrected and updated by solving the bivariate root-finding problem. Building upon this, a time-coordinated reentry guidance framework is established by integrating heading angle corridor-based lateral guidance with a cooperative flight time determination method, enabling rapid online generation of guidance commands. Finally, numerical simulation results demonstrate that the proposed algorithm satisfies all the constraints for time-coordinated reentry, with high guidance precision and strong adaptability. Compared to numerical integration methods, the neural network achieves comparable prediction accuracy with only 10% of the computational time. Monte Carlo simulations further confirm that the algorithm maintains excellent robustness under uncertainties in initial states and aerodynamic parameters.
