摘要
舵机控制系统是无人飞行器中的一个重要设备。首先介绍了一种利用μPSD3234A单片机设计的舵机控制系统,产生4路PWM信号控制JR舵机。该系统通过RS232接口与上位机进行通讯,采集飞行传感器信息,并接收上位机的控制命令。根据控制命令产生相应的控制信号,实现对JR舵机的控制。经试验检测,控制精度和稳定度均达到了舵机控制的要求。
Servo controller system plays a very important role in mini unmanned aerial vehicle(UAV).This paper introduces a servo control system using μPSD3234A MCU,which generates 4 pulse-width modulation for controlling of JR servos.The system communicates with upper subsystem by RS232 interface,collects information of sensor in UAV,and receives control commands from upper subsystem.The signals are generated based on relevant control commands,and realizes the controlling of JR servos.By the test of experiment,the control precision and stability are all reached the requirement of the controlling of servos.
