A precise high-speed tracking and pointing control system of camera based on FPGA : Closed loop feedback control system to control the remote sensing camera lens moving

摘要

This paper designed a precise high-speed tracking and pointing Control system of Camera based on FPGA. The control system can control the remote sensing camera lens moving accurately and flexibly. The system had the function of control angle position control speed and stable speed regulation. We used the step motor to be actuator. The acceleration and deceleration process was stable, effective and high precision. The system adopted the closed loop feedback method. Using the FPGA simplifies the structure of motor control system, reduced the system cost. The modular system can be widely used in various fields.
