| 摘 要： | 将ASIC技术与传统的控制方法相结合，引出了用FPGA来实现单回路数字PID控制器的设计思想。本文在LP3900万用数位逻辑发展系统上用Foundation2.1电路设计软件和Xilinx Spartan系列FPGA XCS20—208来设计和实现单回路数字PID控制器，其中A／D转换和D／A转换部分分别采用AD7394和LTC1296芯片，最后的仿真结果表明了该方案的可行性和设计模块的准确性。

| Abstract: | By combining the ASIC technology with the traditi on al control method, an idea of PID controller on FPGA is presented. Based on the laboratorial board LP3900FPGAXCS20208 produced by the LEAP ELECTRONIC CO.LTD and using its Xilinx Spartan FPGA chip, the simpl est system to produce PID professional chip in FPGA is established, which is imp lemented on the software Foundation2.1. A/D convert is performed on chip LTC12 96, while D/A convert is achieved on chip AD7394.Simulation results show the ef fectiveness of the method. |
