摘　　要：针对多轴运动数控系统的工作特点和发展趋势,提出一种基于FPGA的PCI局部总线的步进电机伺服控制卡设计。设计中采用了适合FPGA的直线插补和梯形加减速控制算法。该控制卡应用于重庆某精密机械公司的工业标记系统,能够驱动256细分的驱动器平稳运行,噪声小。In view of multi-axis CNC system＇s work characteristics and its development tendency,a design of PCI servo control card based on FPGA is proposed in this paper. Interpolation arithmetic for FPGA and trapezia velocity control are used in the design. The control card can drive the 256 subdivided driver smoothly in little noise when it is used at some machinery company in chongqing.
