摘要: 伺服电路是整个原子频标系统的控制核心部件,在传统技术基础上提出一种改进的伺服方法:改进了直接数字合成实现综合器的大范围智能控制、同步鉴相功能。通过上述方案的改进,一方面克服了传统技术上的脱锁问题,另一方面使原子频标具备了工作状态的指示判断功能。

Abstract: Servo circuit is the core control component of the atomic frequency standard. In this paper,an improved servo system method is described in detail of DDS achieves the wide range synthesizer control,and synchronous phase based on the traditional technology. Through the mentioned improvement,on one hand,overcomes the lock losing problem in traditional technology,on the other hand,makes the atomic frequency standard have the function of function mode indication and judgement.

Key words: atomic frequency standard, servo, locked indication
