    • Vibration vision measurement and wavelet neural network control of flexible hinged plate

    • 航天器供能太阳帆板类柔性薄板结构的振动问题得到了新的解决方案。专家构建了双目视觉系统的振动测控实验平台,利用双目立体视觉技术检测振动,并设计了自回归小波神经网络控制器(SRWNNC)来抑制振动。通过对双目视觉系统的标定和图像处理算法,成功获取了振动信号的三维坐标。实验结果表明,双目视觉传感器对振动信号的检测精度小于0.1 mm,而SRWNNC的抑振效果也优于大增益PD控制器。这一研究不仅验证了双目视觉振动检测和SRWNNC抑制振动的准确性和有效性,也为航天器柔性薄板结构的振动控制提供了新的解决方案。
