Software and hardware complex for simulation modeling of a multirotor UAV flight

The article proposes a hardware-software complex for flight simulation of a multirotor unmanned aerial vehicle, which allows near real-time operation in the MatLab / Simulink software package. To obtain adequate control characteristics and estimate flight time, simulation models of propellers and brushless motors have been developed and verified. The unmanned aerial vehicle system model allows to combine various propellers, brushless electric motors, batteries; to test control system software in automatic, semi-automatic, manual control modes, with various combinations of external factors, such as flight altitude relative to sea level, wind direction and force; as well as to simulate errors in determining coordinates and altitude. The results of the work were used for the flight modes test of a real multirotor unmanned aerial vehicle.
