ADAPTIVE-ROBUST CONTROL DESIGN METHODS

This paper presents a design procedure for control systems implemented on dynamic variable and nonlinear processes. The proposed adaptive-robust control strategy is taking into account both adaptive control advantages and robust control benefits and is using the same integral criterion for the identification of the process and for the control algorithm design. An optimality integral criterion and an appropriate measure for degradation of the system performances due to variation of the dynamic model are introduced. This inteogral criterion is expressed in a direct form, through a cost function, defined in the model and the controller parameters’ space. For the minimization of this nonlinear function, a numerical mathematic nonlinear programming method is used. The theoretical approach presented in this paper is validated on a close loop control system, the application being developed in Visual C#

Contributions of Florin Gheorghe Filip in Information Science and Technology

Romanian scientist Florin Gheorghe Filip was born in 1947 and this year he turns 70. F.G. Filip is an engineer and Ph.D. in control engineering and computer science. Still very young, he became corresponding member of the Romanian Academy in 1991 (when he was only 44 years old), and, at 52 years old (1999), become full member in the highest learned society of Romania. From 1970 to 2000, he worked at the National R&D Institute in Informatics Bucharest (ICI). For 10 years, during 2000-2010, he was Vice President of the Romanian Academy. In 2010, he was elected President of the "Information Science and Technology" section of Romanian Academy. At present, he is the director of the Romanian Academy Library. His fields of scientific interest have been: decision support systems (DSS), large-scale systems control and optimization, technology management and foresight and IT application to cultural domain . He has authored/co-authored over 300 technical papers, 13 monographs, and edited/co-edited 24 contributed volumes
