摘 要电气传动分成不调速和调速两大类，调速又分交流调速和直流调速两种方式。不调速电动机直接由电网供电，但随着电力电子技术的发展这类原本不调速的机械越来越多地改用调速传动以节约电能(节约 15%～20%或更多)，改善产品质量，提高产量。在我国 60%的发电量是通过电动机消耗掉的，因此调速传动是一个重要行业，一直得到国家重视，目前已有一定规模。 随着自动化技术的飞速发展 ，电气传动控制系统也日新月异，电气传动控制系统的概念从出现以来，电气传动控制系统又有了新的发展。电气传动控制系统是近年来引起人们很大兴趣的一个领域：它的研究目标是用机器，通常为传动控制系统、电脑等，尽可能地代替人的体力活动，并且争取在这些方面最终改善并超出人的能力；其研究领域及应用范围十分广泛、例如，自动控制、人工智能、PLC 控制系统、智能机器人等等。电气传动控制系统的研究是通过他的原理及其应用而为人类社会的进步作出贡献。关键词：传动控制；自动控制；PLC 控制；智能控制；电气传动；数字控制； ABSTRACTThe electric drive is divided into two major categories of non-governor and governor, the governor was divided AC governor and DC speed control in two ways. Speed motor directly from the power grid, but with the development of power electronics technology such as the original speed mechanical increasingly switch to variable speed drives to save energy (savings of 15% to 20% or more) to improve product quality and increase production. 60% of the generating capacity in the country is consumed by electric motors, variable speed drives is an important industry, has been to get national attention, there are a certain size.With the rapid development of automation technology, electric drive control system with each passing day, the concept of electric transmission control system since the emergence of electric drive control systems, there has been a new development. The electric drive control system aroused great interest in recent years: its research goal is to use the ma...
