乳酪化学分析方法.第11部分:经过处理的乳酪和乳酪制品中添加的柠檬酸盐乳化剂和酸化剂ph值控制剂含量计算 - On the theory , the predictive function control method based on the state space is discussed and the simulation results validate the pfc method ' s advantages on robust and anti - jamming comparing with pid method by computer simulation . the application research includes the application of the software of predictive function control ( apc - pfc ) and the software of the multiple - variables predictive control ( apc - hiecori ) . the former were applied in the temperature control chlorinating process and ph control in the process of zymolysis of penicillin , the latter were applied in the advanced control of reclaim equipment of lox in china petroleum & chemical corporation yangzi petrochemical co . , ltd
本文主要从理论和应用两方面对预测控制方法进行了研究，理论方面主要是从预测函数控制的基本原理出发，研究了一般情况下的基于状态空间描述的预测函数控制策略，并通过计算机仿真验证了pfc算法比常规pid算法具有更好的鲁棒性和抗干扰性：在实际工业过程的应用上，又分为两类算法及软件的应用，预测函数控制策略及apc - pfc软件的应用主要以聚乙烯氯化过程的温度控制和青霉素发酵过程的ph值控制为主，多变量预测控制算法和apc - hiecon软件的应用主要以扬子石化公司的液化气回收装置先进控制为主。
