The project directed by Prof. Liu Xinggao was awarded Zhejiang Province 2nd Prize of Sci & Tech. Researches on energy saving control of Internal Thermally Coupled Distillation / Air Separation Columns, optimal control of propylene polymerization process and intelligent modeling and system identification of energy saving in chemical processes are carried out. Several nonlinear model, control strategies and optimization approaches of energy saving of Internal Thermally Coupled Distillation / Air Separation Columns, several novel prediction models of melt index in propylene polymerization process, and several novel approach of cooperative optimization of swarm intelligence and multi-rate hierarchical identification are proposed. The related contributions include 103 articles indexed by SCI, 19 national invention patents and 20 national computer software copyrights granted.
