As the existing analog control systems of DC servo motor are of low stability and need high-accuracy devices,a digital control system based on DSP is proposed,and the corresponding implementation schemes of DSP control algorithm are discussed in detail. In the proposed system, a PI adjustment manner is adopted, and a DSP is used as the core for the digital control. Thus, the disadvantages of the existing control systems, namely complex structure, low control accuracy and high cost, are overcome. Moreover, with the help of the proposed system, some advanced control theories can be effectively applied to practical engineering, and the performance and accuracy of motor control are remarkably improved.
