根据太阳电池翼的结构固有频率和模态阻尼参数,设计基于零位移算法的输入整形器,用于抑制太阳电池翼调姿后的残余振动。分别用太阳电池翼有限元模型的动力响应仿真和缩比模型试验测试,验证整形后的转角输入函数驱动太阳电池翼调姿能抑制残余振动,且具有较强的鲁棒性。
According to the structure natural frequency and modal damping parameters of the solar cell wing, an input shaper based on the zero displacement algorithm is designed to restrain the residual vibration after the solar cell wing is adjusted. The finite element model of the solar battery was used to simulate the dynamic response and reduce the model test respectively. It is verified that the reshaped attitude driven by the rotated angle input function can suppress the residual vibration and has strong robustness.
