Steady-state Objective Calculation for Constrained Predictive Control Systems Based on Goal Programming

ZHENG Yi,WANG Bai-ping,LI Shao-yuan(School of Electronic,Information and Electrical Engineering,Shanghai Jiaotong University,Shanghai 200240,China)  
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.
