摘要: 本文叙述了单板计算机控制的直流电动机可逆调速系统.本系统用计算机软件代替原模 拟系统中的PI调节器、逻辑切换装置及其它模拟硬件,使可控硅触发器的输出数字化,从而实 现了全数字化控制.本系统不仅节省大量硬件,且调整方便,运行可靠性大为提高.Abstract: In this article, the basic research concering the speed control system of a DC motor by a single board computer is dealt with. In this system analogue hardware such as PI regulators, logic circuits etc. in a double-closed circuits SCR-D system are fully substituted by the computer software. The triggers of the thyristors are also digitized by the computer software. Thus a fully digitized control system with the advantages of less hardware components, easy to adjust and higher reliability is obtained.
