Model Reference Adaptive Control of a Permanent Magnet Brushless DC Motor for UAV Electric Propulsion System

A Novel Approach for Brushless DC Motors Characterization in Drones Based on Chaos

“…It has rotating magnets with magnets axially facing the armatures, e.g., hub-type cycle dynamos [6]. They are vastly used by industry in machines, e.g., [7], and as the main alternative for electrical vehicles such as commercial UAV [8][9][10].…”

“…There are some possible causes of failures in BLDC motors, like stator, rotor, bearing and inverter faults [11], and many approaches to implement fault tolerant aerial vehicles. Solomon [9] shows that the speed control scheme primarily made up of standard proportional integral controllers presented loss of altitude and exacerbate thrust when the system was operated in speed control mode. Thus, he proposes a new solution based on Model Reference Adaptive Control (MRAC) to improve the speed control and improvement in flight performance of the UAV system.…”

Experimental Assessment of Various Batteries and Propellers for Small Solar-Powered Unmanned Aerial Vehicle

“…Thus, this preliminary study intended to investigate performance optimization of the electric propulsion system of solar-powered UAVs. A poor combination of battery, electric motor, and propeller usage will affect the endurance and range of solar-powered UAVs directly, as discussed by Ostler, et al [9], Stepaniak, et al [10], Solomon [11], and Gohardani [12]. Hence, the proper selection of the propulsion system components to be used is important, as discussed by Gur and Rosen [13] and Smith and Rajendran [14].…”
