摘　　要：利用现场可编程门列阵设计一款五轴步进电机运动控制卡,采用了NiosII软核CPU+FPGA的硬件设计方案:利用NiosII软核CPU运行控制程序,利用FPGA来实现数字差补算法和细分驱动;采用了数字积分算法和正弦波脉宽调制细分驱动技术。测试结果表明:该运动控制卡具有电路紧凑、性价比高而速度快、精度高和实时性强优点。A kind of high-speed motion control card for controlling 5-axis stepping motor was implemented by FPGA, and a kind of design scheme based on NiosII ＋ FPGA was proposed. The NiosII soft core CPU was used to run controlling program, and the algorithm of digital differential and subdivided drive were implemented by FPGA. The algorithm of digital differential analyzer （DDA） and technology of SPWM were adopted in the card. Testing result shows that the card has the advantages of circuit compact, high ratio of price/performance, high controlling precision and strong real-time performance.
