高精度速率转台的速率精度均优于0.1%。通常采用数字——相位系统实现调速控制。本文阐明了转台速率性能的定义;分析了数字——相位调速系统具有调速范围宽、调速分辨率高、速率稳定性好、速率精度高等特点;论述了转台速率波动与测角元件(感应同步器)的细分误差和极对数的乘积成正比的定量关系;并指出用“1°间隔定角计时法”检测转台速率波动的局限性。
Accuracy rate turret speed accuracy is better than 0.1%. Usually digital - phase system to achieve speed control. This paper illustrates the definition of turntable speed performance. It analyzes the characteristics of digital speed control system with wide speed range, high speed resolution, good speed stability and high rate accuracy. Induction synchronizer) and the number of pole pairs is proportional to the quantitative relationship; and pointed out that “1 ° interval angular meter method” to detect the turret speed fluctuations in the limitations.
