摘要
战术导弹气动参数辨识是飞行器气动参数辨识的一个重要分支。文章利用极大似然准则,采用遗传算法对导弹气动参数进行离线辨识,此算法避免了传统辨识方法可能出现的数值问题,使辨识准确性明显增强。最后给出了该结果的仿真试验。
The tactical missile aerodynamic parameters identification is an important branch of flight vehicle aerodynamic parameters identification. Based on the maximum likelihood criterion, this article uses the genetic algorithm to carry on the off-line identification to the missile aerodynamic parameters, this algorithm has avoided the value question which the traditional identification method may appear, and makes the identification more accurate. Finally the article gives the results of simulation experiment.
