Abstract:

As one of the representative industries of new-quality productive forces， the low-altitude economy can not only foster new economic growth points， but also drive the development of multiple related industries such as low-altitude manufacturing， low-altitude flight， low-altitude support and integrated services. It is of great significance in boosting economic growth and promoting technological innovation. Intelligent obstacle avoidance decision-making and safety control of low-altitude Unmanned Aerial Vehicle （UAV） are prerequisites for ensuring the efficient and safe transportation of low-altitude UAV， and have thus become one of the research hotspots in the field of low-altitude economy in recent years. Based on existing research achievements at home and abroad， this paper reviews the research status of intelligent obstacle avoidance decision-making and safety control technologies for low-altitude UAV and prospects their future development directions. Specifically， it summarizes the key technologies that have been addressed from the aspects of safety obstacle avoidance decision-making for low-altitude UAV， safe path planning， safety control of low-altitude UAV under satellite signal denial， safety control of low-altitude UAV under disturbances， and safety control of low-altitude UAV under multiple constraints. Finally， the future research directions of intelligent obstacle avoidance decision-making and safety control for low-altitude UAVs are prospected.

Key words: low-altitude economy, low-altitude UAV, obstacle avoidance decision-making, flight path planning, safety control, anti-disturbance control, multi-constraint control
