摘要:

设计了一种基于DSP和PowerPC的开放式伺服控制系统,该系统主要采用TMS320C6713微控制器实现通信及控制算法的运算。硬件部分介绍了双端口RAM电路、电源电路及复位电路,并提出了PowerPC端和DSP端基于双端口RAM芯片进行通信的方法。软件部分每400 us进行一次伺服采样运算并通过PID调节进行误差补偿。通过实验对PID算法部分进行参数整定及误差分析,结果证明,该伺服运动控制系统可达到良好的控制精度。

Abstract:

This paper introduces the design of open servo control system based on DSP and PowerPC. This system mainly uses TMS320C6713 micro controller to realize communication and control algorithm. The hardware part introduces the design method of dual port RAM circuit, power circuit and reset circuit, and puts forward a communication method based on dual port RAM chip for PowerPC and DSP ports. In the software part, once a servo sampling operation is performed on each 400us and the error compensation by PID adjustment. Finally, the experiment on the part of the PID algorithm is carried out parameter tuning and the error analysis. And the results show that the servo motion control system can achieve good control accuracy.

Key words: open CNC system, servo motion controller, DSP, PID
