摘要： 在MPC稳态目标计算和动态优化控制两级结构基础上,研究了系统优化可行性与目标协调问题. 采用目标优先因子描述约束调整的优先级，并将目标协调问题转化成目标约束满足问题，从而解决了稳态目标计算中同时考虑约束调整与目标协调问题.以壳牌重油分馏塔标准问题为例进行仿真，结果表明了该算法的有效性.

关键词: 预测控制, 约束优先级, 目标优先级, 目标规划

Abstract: In the procedure of steadystate objective calculation, the soft constraints adjustment and objective relaxation were required for getting satisfying results when the optimization problem is infeasible. The goal priority factor was introduced to describe the priority of the constraints and objectives; thereby the soft constraints adjustment and objectives coordination were solved systemically in realtime steadystate objective calculation. Simulation was processed with the example of the shell heavy oil fractionators benchmark problem, and the result shows the validity of the proposed algorithm.
