Flying qualities based time-varying stability augmentation system design for tiltrotor conversion control
《Chinese Journal of Aeronautics》2024年第11期366-385,共20页Chen WANG Wenqian TAN Liguo SUN Junkai JIAO 
co-supported by the Fundamental Research Funds for the Central Universities of China(No.YWF-23-SDHK-L-005);the Aeronautical Science Foundation of China(Nos.20220048051001,20230013051002);National Key Laboratory of Science and Technology on Rotorcraft Aeromechanics;China(Nos.61422202205,61422202106);the 1912Project,China。
Tiltrotors have three flight modes that pose control problems and quality defects during the conversion process.To address this,a novel flying qualities-based time-varying stability augmentation system is designed to ...
