转台数字锁相系统最高极限速率的确定方法

Method of Determining Maximum Speed Limitation of Digital Phaselocked Speed System of Test Table

数字锁相速率系统实质是一个非线性系统。确定其最高速率极限是设计者十分关心的问题。本文采用求锁相环非线性系统极限环频率的方法确定了系统的速率极限，并给出了计算公式。用该方法对某转台速率系统进行了计算，结果证明了此方法的有效性。

Digital phaselocked speed system is actually a nonlinear system.The determination of the maximum speed limitation is the problem that is concerned by the designer.In this paper,by deriving the limit loop frequency of the system,the speed limitation is determined,and the calculating formulas are given.The effectivity of this method has been approved by using on a certain test table speed system.
