摘要： 在非惯性系下建立太阳电池翼的运动方程，完成双输入整形器的理论推导，解决两轴转动太阳电池翼调姿后的残余振动问题。双输入整形器根据太阳电池翼的结构固有振动特性，包括固有频率、阻尼比、质量阵和模态向量，针对每个转角输入设计基于连续传递函数的双输入整形器，用于抑制两轴转动太阳电池翼调姿后的残余振动。通过太阳电池翼弯曲－扭转两轴转动有限元模型动力学仿真，验证整形后的转角输入函数驱动太阳电池翼调姿能有效抑制残余振动，且在电池翼结构参数有所震荡的情况下具有较好的鲁棒性。

Abstract: The kinematic equations of a solar array are built in a non-inertia coordinate system and the double-input shapers based on continuous transfer function are designed and further applied to suppressing the residual vibration of the solar array in two rotation axes. Both rotation input signals are shaped respectively. Design parameters of the input shapers only depend on the natural vibration characteristic of the structural system including the natural frequencies, the damping ratio, the mass matrix and the modal vector. A finite element model is developed to simulate the dynamics response of the solar array in two rotation axes. Through the simulation, it is verified that the shaped rotation input signals to drive the attitude adjustment of the solar array can effectively suppress the residual vibration and the solar array has a good robust performance even if the parameters of the structure are not valued exactly.
