摘要
大时滞现象存在于许多工业生产过程中,诸如建材行业中的水泥窑煅烧过程、玻璃熔窑的传热等,克服大时滞是改善此类过程控制质量的一个关键问题.本文综述了近三十多年来关于大时滞系统控制的现状、进展及有关问题,并简介一种对时变大时滞系统较有效的自适应控制算法.
Dead-time appears very commonly in industrial processes. For instance, in building material industry, it exists in the calcining process of cement kiln and in the transmitting heat process of glass smelting furnace, etc. In order to improve the control equality, it is very important to overcome difficulties arisen from deadtime. In this paper, the present status and the developments in the last thirty years for controlling dead-time systems were briefly reviewed. An adaptive control algorithm for controlling time-varying dead-time system was also presented.
