In Automatic Landing Flight Experiments (ALFLEX), side-slip angle control is adopted, but damping of the ADS Pitot probe was less than the predicted value. As a result, the lateral-directional motion has an unstable mode caused by measurement noise of the ADS side-slip angle. In this report, a new method to compensate ADS side-slip angle using inertial velocity information is proposed. The method is evaluated using mathematical simulation of ALFLEX vehicle and compared with a simpler method in which measurement noise is removed by a low-pass filter. The results are as follows: (1) in a simple method using a low pass filter, the motion of the vehicle diverges since inertial motion is also filtered; and (2) in a newly proposed method, the vehicle can fly under turbulence, and it is proved that the method is useful.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
