A subdivision driver control system of four-phase stepper motor based on FPGA and single-chip processor is designed in this paper. Using the PWM subdivision drive signals generated by FPGA,combined with STC89C52,the functions of system such as speed regulation and direction control are realized. The simulation of PWM control signals and the test of system are done. The results of simulation and experiment show that the system is of better controlling precision and stabilization,and has preferable practical value.
