摘　　要：为保证步进电动机运动控制精度高、响应快、低成本、操作简单,研制了一种性价比高的步进电动机运动控制系统。以高速单片机为主控器,增强型并行口(EPP)为通信接口,FPGA实现脉冲信号发生器,利用PC丰富的资源,实现了步进脉冲信号连续、稳定可调和联动插补。实验证明,控制系统用于焊缝扫查跟踪控制时,其焊缝扫查偏差小于1 mm,定位准确、实时可靠、控制灵活、速度运行宽、抗干扰性能强、人机接口方便,具有良好的适应性和自保护能力。To improve the motor driver＇s load -property and the potency of stepping motors, a stepper controlling card was developed. By using the technology of the control theory, the computer network,EPP,FPGA （Field Programmable Gates Array） and single chip microcomputer, the system realized producing stable and continuous adjustment impulse signal. It was proved that not only had the controlling card high transport rate ,nice real - time control and convenient man - machine conversation,but it had nice adaptation and self- protection ability.
