摘要
针对生产过程控制系统中经常出现的问题及要求（被控变量失控，优化操作变量，保证产品质量、卡边操作等）给出了一种实用的协调控制策略。此协调控制策略将先进的预估控制算法和实用的常规ＰＩＤ算法结合起来，在保证控制目标的同时，使操作变量尽量维持在最优值（区域）上，在两个炼油厂的催化裂化装置（ＦＣＣＵ）主分馏塔产品质量优化控制系统中得到了应用。
Abstract An usefull coordinated control scheme for the problems and requirements(such as variable runaway,operating variable optimized,products quality guaranteed and critical operation,etc)that frequently crops up in production process control system is given out.The advanced predictive control algorithm and usefull routine PID algorithm is integrated by the scheme.In the meantime of guaranteeing control target,the operating variable is held in the field of optimeum value.The actural result proves that the scheme is reasonable and usefull.
