伺服系统的发展经历了从液压、气动到电气的过程，而电气伺服系统包括伺服电机、反馈装置和控制器。在20世纪60年代，早是直流电机作为主要执行部件，在70年代以后，交流伺服电机的性价比不断提高，逐渐取代直流电机成为伺服系统的主导执行电机。控制器的功能是完成伺服系统的闭环控制，包括力矩、速度和位置等。我们通常说的伺服驱动器已经包括了控制器的基本功能和功率放大部分。虽然采用功率步进电机直接驱动的开环伺服系统曾经在90年代的所谓经济型数控领域获得广泛使用，但是迅速被交流伺服所取代。进入21世纪，交流伺服系统越来越成熟，市场呈现快速多元化发展，国内外众

多品牌进入市场竞争。目前交流伺服技术已成为工业自动化的支撑性技术之一。
