A Study on Feedforward Control Technology of Large Aperture Narrow-beam Antenna
With the gradual maturity of millimeter wave communication technology,the demand for high frequency and high speed satellite load data transmission is increasing.Based on the characteristics of high dynamic narrow beam of wave satellite signal,stable tracking under high dynamic condition of ground servo system becomes the key to ensure data quality.Considering that the current dynamic characteristics of the antenna servo control system cannot meet the stable tracking of narrow beam signals,it is necessary to make adaptive improvements to the servo control model.Analyzes the dynamic characteristics of composite control for the special requirements of tracking large aperture narrow beam antennas,and proposes simulation models based on engineering ap-plications to optimize practical composite control schemes,meeting the high-precision and stable tracking requirements of high dy-namic narrow beam antennas.It provides improvement plans for subsequent high-precision ground tracking of large aperture narrow beam antennas.
