Abstract

The space data transmission antenna system is an important channel for the telemetry data transmission of the satellite platform to the ground. Therefore, the logarithmic antenna has high requirements for the pointing stability to the ground. The pointing accuracy of the data transmission antenna is seriously affected by the vibration of the satellite platform. Therefore, this paper analyzes the vibration of an orbiting spaceborne data transmission antenna, models, simulates, analyzes and calculates the logarithmic transmission antenna, optimizes the antenna system structure based on this, and designs a fuzzy adaptive PID control system under decentralized control for closed-loop control, The simulation test of the antenna system under the real vibration environment is carried out through the vibration test. The results show that the antenna system has stable performance and can effectively suppress the vibration, which verifies the reliability and feasibility of the antenna system. At present, the data transmission antenna has been put into orbit with satellite launch, and its performance indexes are stable, the research results can be used as a reference to improve the vibration safety of relevant spaceborne antennas.
