摘　　要：针对柔性化制造的要求,构建了以DSP+CPLD为基础的数控系统平台。该平台集成度高、稳定性强,能实现生产过程的高速度、高精度要求,实现了基于CPLD的可重构设计,提高了系统的柔性。在控制算法上,采用单神经元PID及CMAC相结合的伺服运动控制算法,仿真显示较常规PID控制有更好的动态特性、控制精度、抗干扰能力。A hardware development platform for the computer numerical control system was built based on the DSP＋CPLD. It is char- acterized by the high integrity and robust stability, meets the requirements of the production process on high speed and high preci- sion. the reconstructable design based on the FPGA was realized to enhance the flexibility of the system, For the control algorithm , which combines single neuron PI9 with CMAC to control system is Used , Indication through the simulation shows that the control algorithm has better dynamic performance,control precision and strong capability of anti-jamming compared to the traditional PID.
