基于DSP的直流伺服电机数字控制系统

摘要

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.%现有的直流伺服电机模拟控制系统存在器件精度要求高、控制稳定性差等问题。为此，提出了一种基于DSP的数字控制系统，并对DSP控制算法的实现进行了详细介绍。该系统采用PI调节方式，使用DSP作为数字化电机控制系统的核心，可以克服旧有控制系统结构复杂、控制精度低、成本高的不足，并能使各种先进的控制理论应用于实际控制中，使电机控制的性能和水平大为提高。
