摘　　要：随着控制技术以及步进电机(Stepper Motor)的发展,现代工业的许多领域对步进电机的需求也越来越大。但是传统的步进电机控制系统多以单片机等微处理器为基础,往往具有控制电路体积大、控制效率低、稳定性差等缺点。利用FPGA控制速度快、可靠性强等特点,利用等步距细分原理和PWM控制技术,设计出了高灵活性、可人机交互、分辨率高的步进电机控制系统。仿真和实验证明,该控制系统高效可靠。With the development of control technology and stepper motor, the demand for stepper motor in many fileds of modern industry is more and more urgent. Anyhow, because the traditional control system of stepper motor mostly depends on microprocessor such as single chip microcomputer （SCM） , it makes the volume of a control circuit big, the control efficiency low and stability low. A high flexibility and high resolution control system of stepper motor which has the ability of man-machine interaction is designed in this paper by utilizing the advantages of high-speed control and high reliability of FPGA, as well as subdi- vision principle and PWM control technology. Simulation and experiment results show that the control system is efficient and reliable.
