基于FPGA的星载铷钟数字伺服电路设计
资料介绍
介绍了伺服电路在铷原子频标中的工作原理,提出了采用数字器件代替场效应管进行相敏检波的方法,设计了基于现场可编程门阵列（FPGA）的数字伺服电路,实现了铷原子频标的闭环锁定。分析和试验结果表明,数字伺服电路可达到与模拟伺服电路相同的短期稳定度。
The principle of the servo circuit in rubidium atomic frequency standard（RAFS） was introduced. A method which replaces the field effect transistor with digital components was proposed to realize phase sensitivity detection.A digital servo circuit based on field programmable gate array（FPGA） was designed in order to lock the closed-loop of RAFS. The analysis and experiment results show that the RAFS with digital servo circuit can get the same short frequency stability as the one with analog servo circuit.
