Abstract: A hardware development platform for the computer numerical control system was built based on the DSP+CPLD. It is characterized by the high integrity and robust stability, meets the requirements of the production process on high speed and high precision. the reconstructable design based on the FPGA was realized to enhance the flexibility of the system, For the control algorithm ,which combines single neuron PID 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.
