三轴台陀螺伺服状态的实现

Implementation of Threeaxis Turntable Gyroservo State

本文阐述了陀螺伺服状态中陀螺作为敏感元件给系统带来的新问题，即带进了陀螺的时间常数及其他问题，以及对于动力调谐陀螺这些问题的处理。为保护陀螺，在大偏差时加入测速机进行阻尼，当小偏差时死区电路自动切断测速机回路以确保伺服精度。文中还介绍了其他提高伺服精度的措施，如增大带宽及抑制干扰等，并对伺服数据进行了分析，说明陀螺伺服状态设计是正确的，实践上是可行的。

In this paper,new problems for system arising from gyro which plays the role of sensing unit in gyroservo state are discussed,i.e. gyro time constant and other problems are introduced into the system.And how to deal with these problems for dynamic tuned gyros is also discussed.Further more,some methods improving servoaccuracy are presented,such as extending the frequency bandwidth and inhibiting the disturbance.Moreover , servo data are given and analyzed , which shows that the gyro loop design is correct and feasible in practice .
