Unmanned Aerial Vehicle Waypoint Guidance with Energy Efficient Path Planning in Smart Factory

In this paper, we study the minimum input energy for an unmanned aerial vehicle (UAV) while maneuvering in a smart factory. The deployment of UAV in a factory environment for wireless communication between sensors to the central controller promises to provide these services of efficient data collection. A UAV has to traverse the path for data collection from sensors and monitors the production line in a factory. The trajectory optimization of UAV is an important parameter for energy efficiency. We consider the UAV flight on the horizontal plane with constant altitude. In our objective, we aim to minimize the UAV traversal path for predefined coordinates with time-bound. To this end, the theoretical model is derived in the form of a discrete-time linear dynamical system (DTLS). To obtain the energy-efficient path of UAV flight, we optimized the input control vector of the derived system. Simulation results showed that the proposed technique of UAV deployment has significant performance.
