以２０辊轧机辊调系统为对象建立了电液ＰＣＭ控制系统的系统模型，提出了ＰＣＭ与二次型性能指标最优控制相结合的组合控制方法，运行结果表明，电液ＰＣＭ控制能够较好完成诸如２０辊轧机辊形调节这类的位置控制，从而有可能发展成一种结构简单，经济实用的控制系统与方法。
The system model of electro-hydraulic PCM control system is established for the roll-milling system of 20-roll mill. The combined control method of PCM and quadratic performance index optimal control is proposed. The running results show that electro-hydraulic PCM control can be better Complete position control such as roll adjustment of a 20-roll mill makes it possible to develop a simple and economical control system and method.
