Design of Servo Control Mechanism for Laser Tracking Detection System

摘要

A servo control system based on DSP+FPGA structure was proposed in this paper in order to achieve better performances of laser tracking system, meanwhile principles of position detection were introduced in details and the modeling as well as simulation for this system was built. FPGA was implemented in this system to sample the signals from detectors and calculate the values of position and velocity from photoelectric encoder. The control algorithm was accomplished by DSP finally. The experimental results show high tracking accuracy, strong ability of anti-interference and fast response.
