基于OPTIMUS的临近空间飞行器再入轨迹优化设计
Near Space Vehicle Entry Trajectory Optimization Design Based on OPTIMUS
摘要
Abstract
A trajectory optimization method with heating rate,dynamic pressure and load constraints is proposed for near space vehicle based on the OPTIMUS optimization software platform.The dynamic model of entry flight is given and reasonably simplified.The optimal bank angle control law is designed then.The system working flow,design of experiment（DOE） and response surface model（RSM） are built up on OPTIMUS platform.The initial guess is obtained using the optimal algorithms on the platform.With benefits of local and global algorithms,a program combining genetic algorithm and pattern search method is developed to optimize trajectory.The simulation results show that the proposed trajectory optimization method based on OPTIMUS can find accurate initial guess rapidly and improve computation efficiency with high precision.关键词
