导弹制导和跟踪用的若干种低成本陀螺稳定的继电式位标器部件,采用了类似的物理结构。永久磁铁是陀螺转子部件的组成部分。陀螺的标称旋转轴与绕有螺旋导线的圆筒轴相重合。通过适当的调制流经螺旋导线的电流,以控制作用在陀螺仪上的进动力矩。仿造了这类位标器的更一般化的模型,导出了运动方程式,区分了主要误差源,并进行了参数估算。因为它是如此经常碰到的结构,而据作者所知,至今还没有发表过这样的分析,希望本文对文献是有益的贡献。
Several low-cost gyro-stabilized relay-type flag units for missile guidance and tracking use a similar physical structure. Permanent magnets are part of the gyro rotor part. The nominal axis of rotation of the gyroscope coincides with the axis of the cylinder around which the helical wires are wound. The precession moment acting on the gyroscope is controlled by appropriate modulation of the current through the helix. A more generalized model of such a classifier is modeled, the equations of motion are derived, the main error sources are distinguished, and the parameters are estimated. Because it is so often encountered in the structure, and to the author’s knowledge, so far have not published such an analysis, I hope this article is a useful contribution to the literature.
