recommendations! Published in 2024 at "International Journal of Robust and Nonlinear Control"

DOI: 10.1002/rnc.7237

Abstract: Prescribed performance control allows preselected transient and steady‐state bounds of formation control performance. However, owing to the predetermined decaying property of performance functions, it is unavailable for the formation tracking problem with dynamic obstacle avoidance.… read more here.

DOI: 10.1109/access.2024.3459963

Abstract: Vision-based algorithms are widely applied to micro-air vehicles (MAVs) because of their limited takeoff weight. Conventional stereo camera requires a large baseline for long-distance detection, which is difficult for MAVs. The rapidly developing, learning-based, monocular… read more here.
