摘要
为了提高步进电机的定位精度,提出了一种基于THB7128和AT89C2051单片机构成的步进电机控制系统。介绍了THB7128芯片的性能特点,给出了控制系统的电路原理图。在此基础上,分析了步进电机升降速的离散控制方法,给出了步进电机升降速控制的程序流程图。经过实际应用证明,该步进电机控制系统方案结构简单、可靠性高、运行平稳、具有良好的矩频特性。
An control system of stepping motor based on THB7128 and AT89C2051 single chip microcom puter was proposed to improve the position accuracy. The performance and characteristics of THB7128 were introduced, and the circuit schematic diagram of the control system was also offered. On this basis, the method of the stepping motor speed control by the discrete method was analyzed, in the last, provided the program flowchart of the stepping motor speed control. From practice, we can bear out that the control system has the characteristics of high performance, high reliability and good torque/frequency characteristic.
