用计算机辅助的根轨迹法综合数控机床的闭环伺服系统

Systhesis of the NC Machine's Closed Servo-loop using Computer-aided Root Locus Method

本文讨论闭环伺服系统的综合问题,提出了用有限个斜坡元素逼近的方立被控对象的算子数学模型,讨论了数控机床伺服的品质指标,以及如何借助于计法建算机确定根轨迹。

This paper deals with the synthesis of a closed servo-loop and an approach using 'limited ramp elements' is proposed and used to define the mathematical operator model of the controlled object.Discussions on the characteristics concerning the servo-loop of a NC machine tool and on how to get the root-locus aided by a computer are also given.
