基于FPGA的自动调谐控制系统

Autotuning Control System Based on FPGA

本文阐述了大功率发射机自动调谐控制的原理 ,对该系统的核心逻辑设计进行了详细说明 .探讨了大功率发射机工作在长波 ( 1 5 k Hz～ 4 0 k Hz)时 ,利用现场可编程门阵列( FPGA)对发射机回路的调谐元件进行控制的逻辑设计的方法 ,实现了在 1 5 k Hz～ 4 0 k Hz之间频率调谐与控制 ,单片机和 PC机之间串口通信 ,为远程监控、管理和提高自动化程度做准备 .

In the paper the principle of high-power transmitter automatic tuning control is elaborated , and its main logic design is amply explained. The paper goes on to tell how to use FPGA to design the logic in controlling the tuning component of the transmitter circuit, when the high-power transmitter is working in long wave band. The design realizes the frequency band's tune and control in 15kHz～40kHz,and also realizes the communication between single chip and PC, which is ready for achieving the purpose of long-distance supervision、management and improving the level of automation.
