Design of Servo-control System on a Moving Base: Pointing Control to Antenna Based on Aeroboat

Antenna's servo-control system based on aeroboat is a 3-loop DA mixed control system composed of position feedback, velocity feedback and current feedback. The system combined with stabilized loop and tracking loop realizes real-time pointing movement of the antenna. To eliminate the effect on aiming at the target of aeroboat motion, the server-control of 3-axis angle position is realized based on the direct current torque motor drive. The system isolates influence of aeroboat's movement effectively, responds quickly, and it has good self-adapting ability to non-linear and time-changing of controlled object.
