Abstract:

In recent years, there has been an accelerated development of technologies and an expansion of the application area of unmanned aerial vehicles. Accordingly, scientists need to consider current trends in development of unmanned aerial vehicles and the current state of research.

Purpose. Review of the main elements of unmanned aerial vehicle drives. Development of a simplified mathematical model of a helicopter-type unmanned aerial vehicle electric drive for assessing the energy consumption and capacity of the unmanned aerial vehicle battery.

Methodology. The proposed model is based on the rotor motion equations of the motors and the fan load equations. It was assumed that all electric drives operate under a cyclic load repeated periodically and defined by the time relations of motor torque reference during the operating cycle.

Findings. Based on the motion equations, torque (frequency) controller equations, and load equations, a simplified mathematical model of a multi-rotor unmanned aerial vehicle drive was synthesized. The developed mathematical model of the unmanned aerial vehicle electric drive was verified using the created simulation model. Transients for torque and speed were obtained and compared for two torque control algorithms.

Originality. The developed “inertial” mathematical model of the electric drive of a multi-rotor unmanned aerial vehicle, compared to the known models, operates with fewer parameters and variables, which speeds up calculations. The developed model takes into account the equations of torque (frequency) controllers of electric drives. Accordingly, this allows computing long-term processes using different control algorithms.

Practical value. The review materials presented in this article may be useful for technical specialists who are starting to work in the field of unmanned aerial vehicle design and development. The developed mathematical model allows evaluating the approximate capacity of the battery for arbitrary motor reference torque schedules, arbitrary battery voltage reference, and the required maximum flight duration.

Keywords: electric drive, unmanned aerial vehicle, mathematical model, motion equation
