摘要
文章介绍了一种基于FPGA的位置式数字PID控制器的设计，该PID控制器由控制模块和运算模块等构成．在Quartus II平台上，利用VHDL编程和调用宏功能模块设计实现。该控制器结构简单，控制明确，可在线编程。经过PID参数整定和控制性能测试，仿真表明，该设计具有较高的控制精度和响应速度，具有较高的实际应用价值。
The design of the position PID controller based on FPGA was introduced. Adopting the Library of Parameterized Modules （LPM） and VHDL of Quatus II software, this PID controller is composed of control module and operation module. The controller is designed with the digital techniques, which has simple structure, accurate control and can be programmed on line. The PID parameter tuning and control performance testing, simulation results show that the design is more precise and effective and has high practical value.
