文章主要介绍了一种基于现场可编程门阵列的比例控制放大器的设计方法。根据设计要求,硬件分为模拟量输入调理子系统、A/D转换子系统、FPGA子系统、功率放大子系统、反馈子系统等。软件通过模块划分,主要分为顶层控制模块、数据包模块、斜坡信号模块、PID模块、串口通信模块,并且利用硬件描述语言来加以实现。本文所使用的软件开发环境为Altera公司的Quartus II以及相应的开发工具。
This paper mainly introduces a design method of proportional control amplifier based on field programmable gate array. According to the design requirements, the hardware is divided into analog input conditioning subsystem, A / D conversion subsystem, FPGA subsystem, power amplifier subsystem, feedback subsystem. The software is divided by module, which is mainly divided into top control module, data packet module, ramp signal module, PID module and serial port communication module, and it is realized by hardware description language. The software development environment that this text uses is Quartus II of Altera Corporation and corresponding development tools.
