Abstract
In order to solve the problem of real-time communication with satellite and large volume of servo control system during ship motion,a servo control system of shipborne antenna based on STM32F103 control chip is designed.The system is small in size,it including rotary slip ring,radiator,power amplifier board and turntable motion control system.During the carrier movement,the servo control system changes the turntable in real time according to the data received from the upper computer to ensure that the antenna is accurately aligned with the satellite in real time.According to the number of PWM pulses sent by the timer,the motor motion is controlled,and the encoder feeds back the motor position,so as to realize the accurate positioning of the antenna turntable.The practical application results show that the shipborne antenna servo control system on board can meet the angle requirements of the target satellite,achieve the required angle,and achieve real-time control,which is of great significance for the study of the communication of the target satellite.
