摘　　要：乘波体高超声速飞行器各个子系统之间具有强烈的耦合效应,飞行包线大,因此,需要在飞行器设计早期就将控制相关分析和设计引入,将控制系统参数与气动、推进、结构系统参数一起作为设计参数,并开发能辅助这个设计过程的软件工具。首先将几何外形用参数集表示,建立乘波体高超飞行器的参数化模型。再根据任务需求,确定优化目标函数,然后寻求在约束条件允许的设计空间内的最优参数集。再将系统可控性、闭环稳定性、鲁棒性和时域性能等与控制相关性能指标作为优化指标,将控制对飞行器设计参数调整意见反馈到优化回路,最终得到综和性能最优的飞行器构型。辅助飞行器设计的软件工具能够根据输入的参数集,自动完成飞行器建模和模型动、静态特性分析,并提供多种控制器设计模板。Waverider hypersonic vehicles have the characteristics of strong coupling between subsystems and the wide range flight envelope. Therefore, the control analysis and synthesis should be integrated into the early stage of vehicle design, the parameters in control system should be optimized as well as the parameters in aerodynamic, propulsion and structure systems in the vehicle design, and the software tool to facilitate the design process should be developed. Firstly, a series of parameters are used to de- scribe the geometric, and a parameterized model of hypersonic vehicles is established. Then, the objec- tive function is determined according to mission requirements, and then optimal parameter set will be obtained by searching variables in design space to satisfy the constraints. Then, the control relaxed specifications, such as eontrolabity, stability, robustness and time-domain performances etc. , are set as the optimization indexes, and the proposal on how to adjust parameters is feedbacked to optimization loop. A optimal vehicle configurations is obtained. Finally, the software, which is used to assist vehicle design, is able to carry out vehicle modeling, analyze static and dynamic characteristics, and provide va- rious controller design templates automatically.
