Electrical Performance-Oriented Multisystem Coordinated Regulation for Active Main Reflector Antennas

Key Points

• To enhance the electrical performance of active main reflector antennas subjected to structural deformations.
• Developed a 'initial state guidance - deep repositioning' coordinated regulation strategy.
• Employed fifth-order smooth interpolation for continuous dynamic evolution paths during adjustments.
• Validated the approach using simulations on a 35 m reflector antenna.
• Achieved zero stiffness impacts during deep repositioning control.
• Overcame beam deflection and sidelobe degradation issues.
• Significantly improved the stability of electrical performance during coordinated adjustments.
