Battery consumption estimation methodology for electric unmanned aerial systems

Abstract This study presents a methodology to estimate the battery consumption of an electric powerplant, based on brushless motors, typically used in light unmanned aerial systems. The models motors through equivalent circuit obtained from their dynamic behaviour. Propellers’ data are taken experimental database. Furthermore, variable speed controller efficiency is considered methodology. All parameters involved model adjusted by minimising mean quadratic error measurements both direct and alternating currents. allows designers predict energy consumption, also if any element powerplant changes, such as or propeller. Thus, it useful for selecting best actual RPAS operation. results current several powerplants show coefficient determination higher than 0.96. Finally, validated means case RPAS, where selected terms endurance.
