三轴台速率状态的鉴相及其速率牵引

Phase Identification and Speed Tracing of Three Axis Test Table

针对三轴台外环轴较大的转动惯量并从分析速率状态的鉴相特性入手，计算了对应外环轴的最高转速时的跟踪时间及最大速度，得到了对于本轴较大的速率不是一步能运行到位，因而提出了速率牵引的方法，即应以５°／ｓ的速率阶递上升。实践证明，此方法是有效的。

In the light of much more rotational inertia at the outer axis of three-axis test table and by analysing the phase identification characteristics of the speed state, the tracing time and maximum speed at the maximum rotational speed of the outer ring are calculated. It is concluded that higher speed can only be achieved by increments of 5°/s instead of one go. Practice proves this . method is effective.
