基于PCI和FPGA的通用伺服控制卡设计

Design of Universal Servo Control Board Based on PCI and FPGA

介绍了基于PCI和ALTERA的现场可编程门阵列(FPGA)进行设计的通用伺服控制卡。PCI局部总线由FPGA完成控制。FPGA中自动完成模拟量输入的采集与存储及模拟量的输出接口,控制卡设计了CAN总线接口。在控制卡中配备了在数字频率口、同步串口通讯、异步串口通讯等多种伺服控制可能用到的数字接口模块,可以根据实际需要进行配置使用,保证了控制卡通用性。该设计具有实时性强、通用性好、应用灵活等特点。

This paper introduces a method of design a universal servo control board based on PCI and Field ProgrammabLe Gate Array （FPGA）. FPGA control the parts of PCI Bus,Analog input data acquisition and output interface are automatically gained by the FPGA.CAN-Bus interface designed in this Board. Several servo control digital interface module,such as digital frequency module,synchro-serial transmission module,asynchron-serial transmission module,are provided in this Board.This control board can be equipped by its own demand,Rapid real time response,good universality and flexible use are gained in this design.
