摘要: 针对控制性能指标是否适用于高超声速飞行任务评价,研究了底层指标的可行性分析方法。首先分析了高超声速飞行器的模型特性,指出底层指标具备高超声速飞行器评价可行性的两点要求。根据上述要求将可行性分析转化为对于任务变量到底层评价指标的映射分析,并提出了一种基于统计实验分析的检验方法。结合高超声速飞行器模型特点,进一步设计了可行性分析流程。然后,分别以静态任务要求和速度、高度跟踪任务要求为例,对应提出频域性能指标和时域性能指标的可行性分析方法。最后针对频域性能指标评价静态任务的可行性设计仿真实验加以验证。仿真结果表明可行性分析的结论与军标观点一致,而且所提出的分析流程具有较好的可实现性。

Abstract: In order to judge whether the control performance evaluation strategy can be applied to hypersonic vehicles, a feasibility analysis of the bottom parameters is addressed. First, the modeling characteristics of hypersonic vehicles are analyzed, proposing two requirements to make sure that the underlying indictors can be applied to control the performance evaluation of hypersonic vehicles. According to the two requirements, the feasibility analysis is converted to the investigation of the map from mission variables to underlying indictors, and a method based on statistical experiments is proposed to analyze the map. Combined with the characteristics of the hypersonic vehicle model, the flow of the feasibility analysis using the underlying indicators for hypersonic flight mission evaluation is further designed. Then, following the analytic flow, hypersonic flight examples of static mission and command tracking are analyzed, proposing frequency domain indicators and time domain indicators. The simulation is conducted for the first example. Static margin and the restricted elevator deflection are set as mission requirements, while damping and frequency characteristics are set as evaluation parameters. Numerical results indicate that the conclusion of analysis is consistent with the view of military standards, and the analysis flow is relatively easy to implement.
