为了验证挠性卫星快速机动控制方法,搭建单轴挠性卫星快速机动试验平台.该平台基于单轴气浮台,令柔性板的挠性频率和刚挠耦合系数与真实卫星的接近.平台充分模拟了卫星在太空中的失重和无阻尼环境,被激发的挠性振动在开环情况下衰减很慢,特别适合挠性卫星姿态快速机动试验.初步的试验包括挠性参数辨识试验和姿态快速机动PD控制试验,仿真结果表明升级后的平台将可以验证快速机动控制方法.
In order to verify the rapid maneuvering control method of flexible satellite, a uniaxial flexible satellites rapid maneuvering test platform is set up.The platform is based on a single-axis flotation platform, so that the flexible frequency and Rigid-flexible coupling coefficient of the flexible plate are close to the real satellites.The platform is full Simulation of the satellite’s weightlessness and undamped environment in space, the excited flexible vibration attenuates very slowly under open-loop conditions and is especially suitable for fast maneuvering test of flexible satellite attitude.Preliminary experiments include flexible parameter identification test and fast attitude Motorized PD control test, the simulation results show that the upgraded platform will be able to verify the rapid maneuver control method.
