【摘要】 针对近空间飞行器(nearspace vehicle)NSV在高超音速飞行时,气动参数变化剧烈且容易受到外界干扰的特点,结合本实验室已建立起来的近空间飞行器动力学模型,建立了比较完整的近空间飞行器6自由度12状态动力学方程和相应的仿真平台,通过对近空间飞行器在不同飞行情况下飞行特性极不稳定的分析,表明所建模型具有复杂的非线性.更多还原

【Abstract】 An anti-disturbance method for nearspace vehicle(NSV)with severely changed aero-dynamic parameters and external disturbance was proposed.Based on the contributions of NSV modeling in our lab and the available literatures, the dynamic equations and the corresponding simulation platform of NSV are presented. Via the analysis of nearspace vehicle dynamics, it is demonstrated that once there was no control input the complex uncertain system is unstable..更多还原
