Title: Stability of interval positive fractional continuoustime linear systems
Abstract: It is shown that the interval positive fractional continuous-time linear systems are asymptotically stable if and only if the lower and upper bounds systems are asymptotically stable. The classical Kharitonov theorem is extended to the interval positive fractional linear systems.
Brief Biography of the Speaker: Prof. dr hab. Eng. Tadeusz Kaczorek was born in 1932 in Elzbieta in the district of Ciechanow. He graduated from the Faculty of Electrical Engineering at the Warsaw University of Technology in 1956. For his dissertations prepared in the field of application of new mathematical methods in electrical engineering he obtained in 1962 the doctoral degree and in 1964 doctor habilitated. In 1974 he was awarded the title of Full Professor. Professor Tadeusz Kaczorek is a well-known and respected scientist internationally. He is pioneering research in the field of discrete dynamic systems with many independent variables and so-called positive dynamic systems. His two monographs in this field has been published by Springer-Verlag in 1985 and 2002 and have gained worldwide recognition. Scientific achievements prof. Tadeusz Kaczorek is impressive not only in the quantitative sense, but - above all - in a qualitative sense. His list of publications includes more than 600 articles in international, national and international congressional and conference materials. If we add to this list 16 monographs and books published in the most prestigious publications, then we will not fully reflect all his achievements in science, its inspiration and its impact. He has also supervised 56 doctoral dissertations and many diploma theses. The international recognition of his scientific achievements is demonstrated by numerous invitations to participate in the program committees of international conferences and foreign journals, as well as lecturing at renowned scientific centers around the world. The international recognition of prof. Tadeusz Kaczorek is accompanied by a long list of honors from various universities. Professor Tadeusz Kaczorek is a member of the Polish Academy of Sciences, the Academy of Engineering in Poland, and in 1988-1991 he was the Director of the Scientific Station of the Polish Academy of Sciences in Rome. In addition, he is a member of the Central Commission for Titles and Degrees, is a member of the Commission of Ethics of the Polish Academy of Sciences and holds important positions in many foundations, such as the Polish Science Foundation. He was also a member of the Scientific Research Committee. On 19 June 2002, the Council of the Faculty of Electrical Engineering, Computer Science and Telecommunications took the initiative to appoint prof. Tadeusz Kaczorek holds the title of doctor honoris causa of the University of Zielona Gora.
