Analysis of nearspace vehicle flight motion modeling

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.
