摘　　要：为了研究采用极大似然法进行飞行参数辨识的效果,利用递推极大似然法对超小型旋翼飞行器遥操作仿真模型控制函数的参数进行了辨识,对极大似然辨识的结果进行了动态性能分析和系统相对稳定性分析,并将其和用传统的最小二乘辨识的结果进行了对比。研究结果不仅验证了仿真控制函数的可用性,而且论证了极大似然法在飞行器参数辨识中的优势。In order to study the effect of using maximum likelihood method on parameter identification of super-mini rotating aerial vehicle, recursive maximum likelihood method was used to identify parameters of the model＇s control function of remote-piloted controlling for unmanned aerial vehicle, and the maximum likelihood identification was introduced. The dynamic performance and relative stability were analyzed, and the simulation results was compared with least square （LS） method. The research results show that the maximum likelihood identification is effective in aerial vehicle system identification.
