摘要
被研究系统的数学模型是调节控制的先决条件。本文以进给驱动系统为例介绍了数控机床数学模型的一种实用测定方法,并给出经过实践检验的适于工程应用的几类数学模型。
Mathematical model of researched system is a prerequisite for controll .Ta-king feed drive system for example, this paper introduced a practical method foridentifying mathematieal model of NC machine tool.Several kinds of mathemati-cal models which are proved by practice and suitable for engineering applica-tion were given.
