近年来,随着廉价,多功能的微机系统的出现和日益广泛的应用,许多采用包括微处埋器和步进电机的控制系统得到了发展。步进电机的线性变速和变速范围较窄且规律单一的非线性变速在应用范围上受到一定限制。如果应用AIM-65单板微型机作为一个可变频的方波发生器,在程序控制下,AIM-65能输出按各种非线性规模变化的变频脉冲,通过驱动电路去驱动步进电机,从而实现位移量按给定规律变化。这在自动控制和自动检测的位移量非线性补偿中都有实用意义。
In recent years, with the advent of inexpensive, versatile microcomputer systems and their increasingly widespread use, many control systems employing micro-burners and stepper motors have been developed. Stepping motor linear speed and variable transmission speed range is narrow and the law of a single non-linear speed change in the application of certain restrictions. If the AIM-65 single-chip microcomputer is used as a variable frequency square wave generator, under program control, the AIM-65 can output variable-frequency pulses varying in various non-linear scales and drive the stepper motor through the drive circuit To achieve the displacement changes according to a given law. This has practical significance in the automatic control and automatic detection of the amount of nonlinear displacement compensation.
