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。
The equations of motion of the solar cell wing are established under the non-inertial system to complete the theoretical derivation of the dual-input shaper to solve the residual vibration problem of the two-axis rotating solar cell wing. Dual-input shaper designs a two-input shaper based on a continuous transfer function for each corner input based on the structural natural vibration characteristics of the solar cell wing, including natural frequency, damping ratio, mass matrix and modal vector, Residual vibration after the solar cell wing is adjusted. Through the dynamic simulation of finite element model of bending and twisting rotation of solar cell wing, it is verified that the adjusted rotational angle input function of the solar cell can effectively restrain the residual vibration when the battery wing structure parameters are oscillatory. Good robustness.
