The drive control system of stepped motor based on FPGA was analyzied by the working principle and designed by verilog language. The system can control the stepped motor according to established angle, the direction of rotation and position control function. Simulation and synthesis results show that the system can not only achieve the stepped motor drive control,but also optimize the traditional system structure,and improve the system of anti-interference ability and stability.It can be used in many application areas,such as Industry Automation,Office Automation etc.%通过对步进电机的驱动控制原理的分析,利用Verilog语言进行层次化设计,最后实现了基于FPGA步进电机的驱动控制系统.该系统可以实现步进电机按既定角度和方向转动及定位控制等功能.仿真和综合的结果表明,该系统不但可以达到对步进电机的驱动控制,同时也优化了传统的系统结构,提高了系统的抗干扰能力和稳定性,可用于工业自动化、办公自动化等应用场合.
