Resumen: Nowadays, the energetic cost of flying in electric-powered UAVs is one of the key challenges. The continuous evolution of electrical energy storage sources is overcome by the great amount of energy required by the propulsion system. Therefore, the on-board energy is a crucial factor that needs to be
further analyzed. In this work, different control strategies applied to a generic UAV propulsion system are considered and a lithium polymer battery dynamic model is included as the propulsion system energy
source. Several simulations are carried out for each control strategy, and a quantitative evaluation of the
influence of each control law over the actual energy consumed by the propulsion system is reported. This
energy, which is delivery by the battery, is next compared against a well-known control-effort-based
index. The results and analysis suggest that conclusions regarding energy savings based on control effort
signals should be drawn carefully, because they do not directly represent the actual consumed energy.
