由于动力电子技术及微型计算机的进步,交流调速驱动系统的使用范围扩大了。交流调速驱动系统已被广泛地应用于几千千瓦的轧钢机、压缩机等的驱动和几瓦的工厂自动化(FA)、办公室自动化(OA)机械的驱动。再加上很早以来的可控硅技术、动力三极管、可关断可控硅(GTO)等电力控制元件的发展,使矢量控制理论、现代控制理论等技术通过微型计算机而得以应用,这就促使交流调速系统在性能方面超过了以往的直流机。本文从叙述厂史背景来阐述以交流驱动为技术中心的脉宽调制(PWM)控制、矢量控制、现代控制理论以及构成这些控制的微型计算机技术的现状与展望。今后,在交流驱动的整个领域里都将看到其应用范围的扩大。
Due to advances in power electronics and microcomputers, the use of AC variable speed drive systems has expanded. AC variable speed drive systems have been widely used in several thousand kilowatts of rolling mills, compressors and other drives and a few watts of factory automation (FA), office automation (OA) machinery drive. Coupled with the early SCR technology, power transistor, turn-off thyristor (GTO) and other power control components, the development of vector control theory, modern control theory and other technologies through the use of micro-computer, which Promote the exchange of speed control system in terms of performance than the previous DC machine. This article describes the history and background of the factory to explain the pulse-width modulation (PWM) control, vector control, modern control theory and the status quo and prospects of the microcomputer-based technology that AC drive as the technology center. In the future, it will see the expansion of its application in the whole field of AC drive.
