Safety-Critical Control under Multiple State and Input Constraints and Application to Fixed-Wing UAV
Donggeon David Oh, Dongjae Lee, H. Jin Kim
This study presents a framework to guarantee safety for a class of second-order nonlinear systems under multiple state and input constraints. To facilitate real-world applications,…
Minimally actuated tiltrotor for perching and normal force exertion
Dongjae Lee, Sunwoo Hwang, Changhyeon Kim +2
This study presents a new hardware design and control of a minimally actuated 5 control degrees of freedom (CDoF) quadrotor-based tiltrotor. The proposed tiltrotor possesses severa…
Design, Modeling and Control of a Top-loading Fully-Actuated Cargo Transportation Multirotor
Wooyong Park, Xiangyu Wu, Dongjae Lee +1
Existing multirotor-based cargo transportation does not maintain a constant cargo attitude due to underactuation; however, fragile payloads may require a consistent posture. The co…
