摘　　要：针对旋翼飞行器本体微型化提出了一种非对称变距方法,同时还对非对称变距的控制特性进行了动态测试研究.利用单片机C8051F020捕捉转过码盘外圈孔时光电传感器发出的脉冲信号,来测得电机转速的动态测速方法,设计了硬件电路、编制了相应的测速软件、搭建了动态飞行实验测试平台.通过大量实验,获得了横滚通道、俯仰通道和总距通道3个操纵通道与主轴电机转速的动态控制特性,以及偏航通道对主轴电机转速的影响.为进一步定量研究这种新型变距方法的机理和自主控制奠定了坚实的基础.In this paper, the way of the new dissymmetrical electronic collector is proposed aiming at the micromation of the MAV. At the same time the control character is studied. Using C8051F020 chip,the pulse signal coming from the hole of the photo electricity coder is captured in order to dynamically test the speed of the motor. The hard- ware circuit, the software of the testing speed and the experiment platform are designed. Through lots of experiments,the dynamic character between the roiling, pitching, yawing, general motor channels and the motor speed are achieved for the further research of the mechanism of the electronic collector control and self - controlled of the MAV.
