It is mainly used to solve the position foll- owed problems, which has a fixed accuracy requirement. These systems are widely applied to military affairs. Such as missile launcher control system, radar antenna control system and so on. Its characteristic is the unknown input. With the development of industrial automation, the application prospect of this system is wider and wider. In this design, the angular servo system is mainly made up of three parts, the angular displacement measurement part, the MCU controller part and the motor drive. After the angular displacement measurement part detects the manual arm’s angular displacement, the controller will control the motor’s rotation according to the detected angle, in order to achieve the purpose that the automatic arm to follow the manual arm. In my design, to display the input angle more intuitively, I add the LED Display part.
