摘要
介绍了使用硬件描述语言(VHDL)对复杂可编程逻辑器件(CPLD)编程,从而实现对压控振荡器(VCO)的输出频率进行自动控制的系统。该系统应用于某导弹导引头直波接收机中,重点介绍了自动频率控制原理和实现方法,包括硬件和软件设计。通过建立数学模型和仿真,以及应用实践,证明该系统简单可靠,使用方便。
Introduces the use of hardware description language（VHDL） to the complex programmable logic device（CPLD） program,thus realizing the voltage controlled oscillator（VCO） output frequency automatic control system.The system is applied to missile seeker straight wave receiver,focuses on the automatic frequency control principle and realization method,including the design of hardware and software.By establishing the mathematical model and the simulation,as well as the application of practice,it is proved that the system is simple and reliable,easy to use.
