【摘要】 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。更多还原

【Abstract】 The electrohydraulic PCM control system is established to analog a 20-roll mill’s roll adjusting system ,and a control way of combining PCM with quadratic optimal control is proposed .Through running on the system, the results show that the control can meet the demand of a kind of position system , such as 20-roll mill’s roll adjusting system ,and therefore,it will be developed as an new kind of useful and ecnomical control system with simple construction.更多还原
