1、Shell重油常压塔
Shell公司重油常压塔是被控制界广泛接受作为多变量系统控制研究的范例模型,该模型是一个有三个产品抽出和三个侧线回流的重油常压塔。如图3-1所示,Shell模型包括三个输入,两个干扰输入,还有七个输出,其中塔顶抽出产品的质量指标y1(干点)和侧线抽出产品的质量指标y2(干点)为系统的被控变量,塔底回流抽出温度y7为辅助变量,另外还有塔顶抽出温度y3,塔顶回流温度y4,侧线抽出温度y5,中段回流温度y6;操作变量包括塔顶产品抽出量u1,侧线产品抽出量u2和塔底回流负荷u3;另外两个变量塔顶回流负荷u5和中段回流负荷u4作为系统扰动。模型的传递函数矩阵用式所示,为一阶加纯滞后形式:
