摘　　要：介绍了采用锁相倍频技术实现系统高精度运转,并突破了单片机电路的频率限制,使系统能够产生更宽的速度变化范围。使用高低压切换型驱动电路来驱动电机。当系统运行异常时自激振荡检测电路能对电路进行校验。速度变化在线控制。In this paper, the high accurate speed control of stepping motor based on PLL is induced. The PLL multiply the frequency, so this system has wider range of speed. This paper also discusses the application of double voltage driving circuit. When the system is running abnormally, the auto-excitation circuit will checkout the system. The speed can update on line.
