Hydrogen Maser Dsp And Fpga-based Digital Servo System

Hydrogen Maser is the extremely high-performance time and frequency standard, which all terms of performance are excellent. It has played an important role in the fields of the fundamental theory, navigation, radar, geodesic survey, astronomical observation, communication etc. With the advance of the space science technology, the development of the compact and portable hydrogen maser with high performance is in great demand.The main content of this paper is to make improvement of the Miniature Passive Maser. The improvement can promote the qualification of the original system and realize intelligent control. Meanwhile, it reduces the size of the circuit board.This paper first analyses the fundamental of servo system and its influence on the frequency stability. And the principle of the PID controller is introduced briefly. Based on the analysis, it computes the parameters of demanded components and makes selections accordingly. Chapter 3 and Chapter 4 give a detailed account of hardware and software design process. After many times of test and a long time of verification, we give the final test results of the system as well as analysis in Chapter 5. The results indicate that the newly designed system has accomplished prospective purpose, and some parameters has surpassed prospective index. At last, the paper gives some of my suggestions about the followed improvement of the system.
