摘要

针对光电稳定平台不平衡力矩难以精确测量的问题,建立了两轴两框架稳定平台的不平衡力矩数学模型,对稳定平台施加线振动激励并测量平台在加速度的激励下产生的角加速度响应,根据辨识算法获得光电稳定平台的质心相对于平台回转中心的偏移量,开展设计和实验,实验表明,辨识出的稳定平台的质心偏移量与理论值平均误差0.058 mm,该方法能够精确评价稳定平台质心的位置,对提升光电平台的稳定精度有较大贡献。

Abstract

In view of the difficulty in accurately measuring the unbalance torque of the optoelectronic stabilized platform, a mathematical model of the unbalance torque of the two-axis, two-frame stabilized platform was established. The linear vibration excitation was applied to the stabilized platform and the angular acceleration response generated by the platform under acceleration was measured. The offset of the center of mass of the optoelectronic stabilized platform relative to the platform's rotation center was obtained according to the identification algorithm, and the design and experiment were carried out. The experiments show that the average error between the identified centroid offset and the theoretical value of the stable platform is 0.058 mm. This method can accurately evaluate the position of the centroid of the stable platform, and has a great contribution to improving the stability accuracy of the photoelectric platform.
