Embedded High-speed Motion Control Device And Its Communication Technology Research

With the development of the mechatronic technology, the system of motion control is becoming more and more complicated. It is difficult for the traditional numerical control computer to deal with such complex motion. The ongoing shift of motion control devices from traditional control systems toward embedded, network and open architecture motion control system is promising to increase process speeds and throughputs.The paper is to research motion control technology and to develope the Embedded Motion Controller that can properly fit the system needs of control in both industrial and military application. At first, the paper gives the motion control strategy, on the base of requirement analysis, the strategy is presented. Because the development of motion controller is playing more important role in our research, the chapter 3 will discuss the constitution and the design of the hardware, with the technology of digital signal processor(DSP) and in-system programming device(ISP), the motion controller can control 4 servo motors simultaneously. A novel data exchange method and the ditail of DSP firmware will also be illustrated in this chapter. By adding a control panel and an I/O board to the Embeded Motion Controller, we can easily buildup a CNC system. The chapter 4 will introduce the realization of the High-speed CNC system based on the Embedded Motion Controller, then introduce the experiment software which to test the data exchange method and the DSP firmware. With the development of Fieldbus and network technology, it is very valuable to find out how to apply the Fieldbus in network motion control application, this content will be explained in the chapter 5 in detail. Finally, the paper will give the conclusions of research and bring forward the future work.
