The results show that the direct mass balance control scheme outstrips the indirect one and can well satisfy the control requirement for both product quality and conversion rate. 结果表明直接物料平衡方案控制品质优于间接物料平衡方案，可在不同扰动情况下满足过程的产品质量和转化率的联合控制要求。
Finally,the features and applications of integrated control systems are introduced. 最后介绍了集成综合控制系统的特点及应用。
