Wind Disturbance Response Analysis and Pointing Control of Hundred-Meter-Class Large-Aperture Reflector Antennas Based on Zonal Wind Pressure Coefficient Prediction

Key Points

• The primary aim is to analyze and improve the response of large-aperture reflector antennas to wind disturbances and enhance their pointing control.
• Developed a dynamic model for the flexible and rigid coupling of large-aperture antennas under random wind input.
• Investigated the effects of wind disturbances on the flexible modal response and corresponding beam offset.
• Implemented a collaborative control method integrating active structure control and pointing compensation.
• Constructed a high-precision zonal wind load prediction model to couple disturbances into the control system.
• Significantly enhanced pointing accuracy of antennas under wind disturbance conditions.
• Improved robustness of the control system, enabling stable operations in complex environments.
