【Abstract】 Considering the requirements of short response time and high positioning accuracy for turntable in image tracking,a position servo control system based on ARM and RDC is presented.In this system,RDC is used to gather the position information from resolver,and the H-bridge circuit based on MOSFET is driven by IR2130.At last,DC motor position servo control is successfully completed by PID control algorithm with speed and acceleration feedforward.The results of experiments show that this control system can satisfy the speed and accuracy requirement in image tracking.更多还原
