摘要:
 文中考虑了一个一般性的以超燃冲压发动机为动力的高超声速飞行器的非线性3自由度纵向动力学模型。此类飞行器常以非最小相位零点为特征，严重限制了升降舵至飞行航迹角控制所能够达到的带宽。为了使高超声速飞行器具有更好的控制相关性能，采用了一种直接将性能指标融入到飞行器设计中的方法对飞行器外形和控制器进行分布式最优化设计，并进行了非线性仿真验证。结果表明，优化飞行器的性能在各方面都有明显改善：油耗减小，升降舵效能提高，发动机壅塞制约降低。
Abstract:
 A nonlinear 3-DOF dynamical model for the longitudinal dynamics of a generic scramjet-powered hypersonic vehicle is con-sidered. This kind of vehicle is often characterized by a non-minimum phase zero,which significantly restricts achievable elevator-flight path angle bandwidth. In order to improve vehicle control-related performance, an optimization method that incorporates performance metrics into the design of vehicle is proposed to implement the decentralized optimization design of hypersonic vehicle configuration and controller. The nonlinear simulation results are given in the paper. The results indicate that optimized vehicle fuel consumption is reduced, efficiency of elevator is increased and the restriction of engine chocking is reduced.
