| Abstract: | A pure hardware design of the speed controller it, step motor based on FPGA and DDS had been introduced. The controller can run independently. DDS technology can switch frequency fastly in phase continuous. FPGA design hardware can restructure. The design principle of each sub-cireuit of the speed controller had been analyzed in details. The validity of the proposed design scheme had been verified by the simulation results. |
