| Abstract: | In this article, a PCI special interface chip PC19052 was used to be a interface bridge of PCI bus and DSP （TMS320LF2407） to carry out the 2-axis motion controller of the perfusion-machine. Firstly, the whole hardware structure of the controller was given, including the interface specification of PCI bus and the DSP expander. Then, application of fuzzy-PID in this system was presented. Through this method of combining PCI and DSP, the fast communication between the controller and the upper PC machine is realized. It takes the full advantage of the DSP＇s features of high-speed and powerful functions to improve the perfusion accuracy. |
