摘　　要：为了解决传统基于PC平台的运动控制器渐显高能耗、高成本、低可靠性等缺点,结合ARM和DSP运动控制芯片特点,给出一种基于ARM微处理器LPC1788和专用DSP运动控制芯片PCL6045BL组合的嵌入式四轴运动控制器。该控制器在硬件上采用ARM+DSP的主从式双CPU结构,并结合ARM在人机界面显示、通信接口方面的优势以及PCL6045BL高控制精度的优点,在软件上通过LPC1788上移植μC/OS-Ⅱ实时操作系统来管理总体的运动控制系统。最后通过圆弧插补实验验证了嵌入式四轴运动控制器具有可靠性高和快速响应等优点。Traditional microcontrollers based on PC increasingly exposed high-cost,high-consumption,low reliability and other shortcomings. According to the characteristics of ARM and DSP motion control chip,a novel embedded four-axis motion controller is designed based on LPC1788 and PCL6045 BL. The controller on the hardware adopts the double CPU master-slave structure of ARM ＋ DSP,combined with the ARM on the man-machine interface display and communication interface,and the advantages of high control precision of PCL6045 BL. On the software through LPC1788 transplanted mu C / OS- Ⅱ real-time operating system to manage the overall motion control system. The results show that the embedded four-axis motion controller can be implemented in 2-axis circular interpolation. The system has a good stability and fast response.
