海洋二号卫星建立正常姿态和轨道的欠驱动控制技术
Underactuated Control Technology of HY-2 Satellite Reestablishing Standard Attitude and Orbit
摘要
Abstract
HY-2 Satellite is China's first ocean dynamics and environment satellite which is in a sun-synchronous regressive frozen orbit and with three-axis stabilized nadir-oriented attitude.After the satellite's seperating from rocket and the deploying of satellite solar panel,plume interference occurred between the solar panel and the thruster for-Z axis attitude control,which caused disturbance torque in+Z axis and at the same time losing control in-Z axis attitude,and furthermore,this positive feedback in Z axis control-loop resulted in the high-speed rotating of the satellite.In this situation the satellite could not reestablish standard attitude and orbit by regular methods.This paper demonstrates in detail the complete satellite-rescuing technologies and processes of HY-2,including the underactuated control technology that makes the satellite detumbling and precessing to sun-oriented attitude,underactuated damping control technology,orbit control technology based on disturbance angular momentum auto-balancing,unloading technology by angular momentum coupling,and finally reestablishing standard orbit and three-axis stabilized nadir-oriented attitude for the satellite.The in-orbit implementation of the above underactuated control technique aboard the HY-2 satellite offers a representative engineering case for underactuated control research,and delivers vital practical guidance for the long-term stable operation of China's long-lifetime,high-reliability satellites.关键词
