This paper focus on a motion control card based on DSP, designed an interface communication between DSP and industrial PC. After a contrast about several methods of communication, this interface take the Dual-port RAM as the final way. This communication method regard the DRAM as the sharing storage unit, use the semaphores of the DRAM chip to prevent visiting the same address at same time on boths port and achieve the high speed communication between DSP and PC104.

Control Accuracy

The servo system consisting of PC computer, multi-axis motion control card, servo driver, servo motor and load was constructed. The paper studied the interpolation principle and edited the procedure of linear interpolation for two axis servo motors. After the communication between PC computer and servo driver based on the motion control card, the paper edited the control interface program calling the interpolation procedure, which could realize the simulation control and real time control to servo motors. The compare results show the control accuracy of the experiment is higher.
