摘要
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.
A test-bed for satellite rapid maneuver is established to verify various control methods.The test-bed is based on the single-axis air bearing bed with its flexible parts＇ frequencies and coupling coefficients close to real satellites.It can be used to simulate the space environment of weightlessness and light damping in which the excitated vibration attenuates very slowly under the condition of open loop,so it is especially suitable for flexible satellite rapid maneuver experiments.There are two finished experiments including parameter identification of elastic modes and attitude rapid maneuver based on the PD method.Simulation results are used to verify the effectiveness of the upgraded test bed for rapid maneuver experiment.
