基于DSP的氢钟高精度控制系统
High Precision Control System in Hydrogen Maser Based on DSP
摘要
Abstract
A control system in passive hydrogen maser based on DSP is introduced.A high precision volt output circuit is designed according to the characteristics of VCXO,such as the high precision control voltage and the wide control range.A high precision voltage output and high speed error signal collection circuit are designed.Then,the driver program is written for the hardware.Moreover,the main routine and digital PID control algorithm are designed to apply to the passive hydrogen maser.The result of hardware test shows that the system satisfies the control needs of the frequency location,and the expected control effect is achieved.关键词
