ABSTRACT
Dynamic real-time control through a remote network is becoming a reality, given the drive of the latest generation of wireless networks. As cloud computing takes on an even stronger role in the industry, the desire to offload time critical processes into the network becomes a possibility. With the combination of cloud edge processing centers, and the UUL standardization for sub-millisecond delay over 5G networks, applications requiring dynamic time critical closed loop control is now an option. With the support of cloud edge processors, advanced complex analysis and processing algorithms, such deep learning engines or video-based approaches, miniature drones can achieve higher levels of capability without the weight or cost requirements. In this paper, we present wireless closed loop control system. The proposed framework is composed of a controller, drone flight receiver and motor control. The delay time from the issuance of the control command to the start of the execution of the control command is only about 4 ms. The proposed solution has been implemented and verified on the research UAV data link system.
