【期刊论文】Identification of a Model Helicopter's Yaw Dynamics
陈大融, Chen Haosheng, Chen Darong
Vol. 127, MARCH 2005, 140-145,-0001,():
-1年11月30日
To identify the micro helicopter's yaw dynamics, the system identification method is used and is proved to be suitable according to the validation results. In order to strengthen the information of the dynamics and reduce the effect of the noise when proc
