基于主被动一体隔振指向平台的柔性航天器高精高稳指向方法
Method of Flexible Spacecraft High Precision and Stability Pointing Based on Active-passive Integrated Vibration Isolation and Pointing Platform
摘要
Abstract
To satisfy increasingly high precision and stability pointing requirements of future as-tronomical satellites and remote sensing satellites,and solve the contradictions between pointing control and vibration suppression,the paper proposes a method to achieve high precision and sta-bility pointing of flexible spacecraft by introducing a Stewart platform with abilities of both vibra-tion suppression and pointing control.The dynamics model of the whole satellite with Stewart platform and flexible appendages is established and active-passive integrated controller is designed.Simulation of transmissibility is done and the pointing control performance of the Stew-art platform is analyzed by numerical simulation.The results show that the platform can meet the demand of vibration isolation and pointing adj ustment at the same time,which can provide a refer-ence for future development of high pointing performance spacecraft.关键词
