Comparative Evaluation Of Investigation Methods For Estimating The Load-Dependent State Of Charge And End Of Discharge Of A Multirotor Uav Battery, Hanna Dibbern, Morten Roßberg, Claudia Werner
Journal of Aviation Technology and Engineering
As the scope of multirotor unmanned aerial vehicle (UAV) applications increases, more attention is being paid to UAV energy requirements, which vary depending on the mission profile. To obtain accurate information about the UAV battery during flight, the idea of a digital twin including a battery state estimation model is promising. For battery state estimation, a Kalman filter combination is the preferred approach in the literature. Comparing different Kalman filters, the unscented Kalman filter has a more accurate estimation for nonlinear systems compared to the extended Kalman filter. In the application of UAV flight with load-dependent flight missions, the comparison …
Model-Based Evaluation Of Energy Systems For Multirotor Uav Based On Batteries And Fuel Cells, Mika Suwe, Martje Eigenseer, Claudia Werner
Model-Based Evaluation Of Energy Systems For Multirotor Uav Based On Batteries And Fuel Cells, Mika Suwe, Martje Eigenseer, Claudia Werner
Journal of Aviation Technology and Engineering
In this study, two multirotor unmanned aerial vehicle (UAV) energy systems are comparatively evaluated via a modelling process, namely a battery electric system and a hybrid fuel cell and battery system. Technical, economic, and ecological evaluation parameters are considered. The evaluation is performed on three different mission types: a 10 km delivery mission, a 3000 m2 facade inspection, and a nine-minute drone show, to represent the transport, monitoring, and event sectors. Results are calculated via a modelling process first simulating the required power profiles for each mission and then simulating both energy systems’ operational behavior during each mission. The resulting …
Model-Based Development Of Multirotor Uav Power Profiles For Performance Investigation Of Different Flight Missions, Mika Suwe, Anna De Groot, Martje Forner, Claudia Werner
Model-Based Development Of Multirotor Uav Power Profiles For Performance Investigation Of Different Flight Missions, Mika Suwe, Anna De Groot, Martje Forner, Claudia Werner
Journal of Aviation Technology and Engineering
In this study, a model is developed for a comparative assessment of three flight missions of multirotor unmanned aerial vehicles (UAVs) based on their power profiles in order to identify future technical research priorities and possible improvements in operational management. The model describes the missions (transport, facade inspection, drone show) based on the maneuver-specific parameters for hovering flight, vertical flight, and horizontal flight and calculates the respective power profiles of the missions based on the input parameters of a reference UAV with a battery-powered electric motor. The power profiles of the investigated missions show that the maximum powers occur during …
