摘　　要：采用PSoC可编程片上系统设计了一个数控运动控制器,由于PSoC具有灵活的可自由配置的模拟、数字资源和输入输出接口以及对多种通信接口的支持,该运动控制器具有良好的可扩展性和可移植性。介绍了系统的整体结构、控制器的硬件模块设计以及直线、圆弧、Nurbs曲线插补方式和速度控制方案的软件实现,使用该控制器控制一台三轴雕刻机进行雕刻,结果表明该系统具有良好的性能。This paper designed a kind of numerical motion controller based on PSoC （Programmable System-on-Chip） which has configurable analog/digital resources and input/output ports as well as a variety of communication interfaces. This numerical mo- tion controller has good scalability and portability. The overall structure of the system, hardware module design, and software design of linear, circular, Nurbs curve interpolation methods and speed control methods are described in detail. Finally, the operating re- suits of a three-axis engraving machine controlled with this numerical motion controller and the system＇s good performance are in- troduced.
