伺服技术的发展

伺服装置是数控系统的重要组成部分。20世纪50年代初，第一台NC机床的进给驱动采用液压驱动。由于液压系统单位面积产生的力大于电气系统所产生的力（约为20:1），惯性小、反应快，因此当时很多NC系统的进给伺服为液压系统。70年代初期，由于石油危机，加上液压对环境的污染以及系统笨重、效率低等原因，美国GETTYS公司开发出直流大惯量伺服电动机，静力矩和起动力矩大，性能良好，FANUC公司很快于1974年引进并在NC机床上得到了应用。从此，开环的系统逐渐被闭环的系统取代，液压伺服系统逐渐被电气伺服系统取代。

电伺服技术的初期阶段为模拟控制，这种控制方法噪声大、漂移大。随着微处理器的采用，引入了数字控制。它有以下优点：①无温漂，稳定性好。②基于数值计算，精度高。③通过参数对系统设定，调整减少。④容易做成ASIC电路。对现代数控系统，伺服技术取得的大突破可以归结为：交流驱动取代直流驱动、数字控制取代模拟控制、或者称为软件控制取代硬件控制。20世纪90年代，许多公司又研制了直线电动机，由全数字伺服驱动，刚性高，频响好，因而可获得高速度。
