| Abstract: | In this paper, the principle for rate system is discussed on the basis of phase - locked loops technique, and the hardware including some key logic circuits is designed by making use of digital signal processor （DSP） and FPGA technique. A controller is designed according to the performance needs, and some simulation results and the block diagram of software are put forward. The whole system is proved stable and reliable and meets the performance requirement. |
