According to an embodiment of the present invention, a motor speed control device of an unmanned aerial vehicle (UAV) comprising a plurality of motors has an effect of enabling stable flight regardless of types of a motor used in the UAV. The motor speed control device of a UAV comprises: an interface unit receiving a pulse width modulation (PWM) signal from a flight controller and transferring a duty cycle to a plurality of motors; and a microprocessor unit calculating the duty cycle by using a PWM signal value and correcting the duty cycle in consideration of voltage of a battery.
일 실시예에 따른 복수 개의 모터를 포함하는 무인 비행체(Unmanned Aerial Vehicle: UAV)의 모터 속도 제어 장치는 비행 제어기로부터 PWM(Pulse Width Modulation) 신호를 수신하고 상기 복수 개의 모터에 듀티 사이클을 전달하는 인터페이스부 및 상기 PWM(Pulse Width Modulation) 신호 값를 이용해서 듀티 사이클을 계산하고, 배터리의 전압을 고려해서 상기 듀티 사이클을 보정하는 마이크로프로세서부를 포함한다.
