The optimal control of the global production indices requires an optimal combination of the production indices, technical indices and the operation of each control loops. In this talk, a hybrid intelligent control strategy is proposed for process industries. This new strategy consists of three control layers, namely the intelligent optimization of the global production indices, the intelligent optimal control of the technical indices and the intelligent process control,The intelligent optimization of the global production indices is composed of the setting model of the technical indices, the predictor of the global production indices, the feedback and prediction analysis adjustment models. The intelligent optimal control of the technique indices consists of the setpoints model of control loops, the prediction of technical indices, the feedback and feedfoword regulators. The intelligent process control is then composed of normal decoupled PID controllers, decoupled nonlinear PID controllers with a neural network feedforword compersator for un-modeled dynamics and a switching mechanism.

Tianyou Chai   received the Ph.D. degree in control theory and engineering from Northeastern University, Shenyang, China, in 1985.

He has been with the Research Center of Automation, Northeastern University since 1985, where he became a Professor in 1988 and a Chair Professor in 2004. He is the founder and Director of the Research Center of Automation, which became a National Engineering and Technology Research Center in 1997 and The State Key Laboratory of Synthetical Automation for Process Industries in 2011. He has made a number of important contributions in control technologies and applications. He has published two monographs´╝î99 peer reviewed international journal papers and around 224 international conference papers. He has been invited to deliver more than 20 plenary speeches in international conferences of IFAC and IEEE. His current research interests include adaptive control, intelligent decoupling control, integrated plant control and system, and the development of control technologies with applications to various industrial processes.

Prof. Chai is a member of Chinese Academy of Engineering, an academician of International Eurasian Academy of Sciences, IEEE Fellow and IFAC Fellow.
