介紹了將達林算法用于電阻爐溫度的計算機控制系統(tǒng)中的結構、原理。闡述了大林算法作為一種直接數(shù)字設計法,適用于被控對象為滯后的系統(tǒng)。電阻爐作為工業(yè)爐窯中的一種常用加熱設備被廣泛應用于工業(yè)生產(chǎn)中。對電阻爐溫度控制精確與否將直接影響到產(chǎn)品的質(zhì)量和生產(chǎn)效率。電阻爐是一種具有純滯后的大慣性系統(tǒng),開關爐門、加熱材料、環(huán)境溫度以及電網(wǎng)電壓等都影響控制過程,傳統(tǒng)的電阻爐控制系統(tǒng)大多建立在一定的模型基礎上,難以保證加熱工藝要求。本文將PID控制算法引入到傳統(tǒng)的電阻爐控制系統(tǒng)中,借此提高其控制效果。設計一個控制精度高、運行穩(wěn)定的電阻爐溫度控制系統(tǒng)是很有必要的。仿真結果表明,該算法優(yōu)于常規(guī)PID算法,是一種較好的控制算法。

Abstract
The paper introduces Dahlin Algorithm ud in resistance furnace’s temperature computer control system. Dahlin Algorithm is a direct digital design method, it adapts to the plant with
delay. Resistance furnace was widely ud in industrial production, the effect of the temperature control of Resistance furnace has a direct impact on product quality and productivity. Therefore, the design of a high-precision control and stable operation of the resistance furnace temperature control system has a high application value. Simulations show this method is better than ordinary PID algorithm, it is a good control method.
