A Performance Evaluation and Analysis Method for Multi-Rotor UAV under Actuator LOE

Abstract

Abstract Loss of Actuator Effectiveness (LOE) reduces the performance parameters of Multi-rotor Unmanned Aerial Vehicle (UAV), which affects the reliability of the mission. However, in practice, researchers used to evaluate the performance of a UAV through lots of flight experiments or by experience, which is normally inefficient and costly. In order to evaluate the performance of UAVs, this paper presents a performance evaluation and analysis method under actuator LOE. First, models are established for the components of a propulsion system, mainly including actuators and batteries. Second, the performance evaluation problem is simplified and decomposed into two sub-problems. performance indices are established by kinetic analysis and then solved, considering the influence of actuator LOE and battery performance. Finally, based on the analysis results, the evaluation method is demonstrated in several cases. The results showed that the evaluation method is effective compared with the simulation results of www.flyeval.com/. In addition, LOE reduces the performance parameters of the UAV, which has a greater impact on the maximum flight speed and maximum cruising distance.
