摘　　要：针对某小型无人直升机研制了一种光传伺服舵机。该光传伺服舵机主要由舵机控制器、伺服电机、减速齿轮、反馈传感器组成,采用主流的PWM脉宽调制控制技术。性能测试结果显示该系统具有实时性好、抗干扰能力强等优点,验证了光传伺服舵机在工程应用上的可行性和可靠性。Servo by light is one of the critical technologies of fly - by - light （FBL） flight control system. This article designs a servo by light for a unmanned helicopter. This system comprises servo controller, DC motor, reducing gears and position sensor. The result of performance test shows that this system has excellent real - time performance and capability of anti - interference, and confirms the feasibility and reliability of servo by light for engineering application.
