System Identification is a well-established field. It is concerned with the determination of particular models for systems that are intended for a certain purpose such as control. Although dynamical systems encountered in the physical world are native to continuous-time domain, system identification has been based largely on discrete-time models for a long time in the past, ignoring certain merits of the native continuous-time models. Continuous-time-model-based system identification techniques were initiated in the middle of the last century, but were overshadowed by the overwhelming developments in discrete-time methods for some time. This was due mainly to the 'go-completely-digital' trend that was spurred by parallel developments in digital computers. The field of identification has now matured and several of the methods (including those developed originally by the author and his collaborators), are now well established and incorporated in the continuous time system identification (CONTSID) toolbox for use with Matlab. This talk presents a perspective of these techniques in a unified framework.
Professor G. P. Rao received the B.E. degree in Electrical Engineering from Andhra University, India in 1963, and the M. Tech. and Ph.D. degrees in Electrical Engineering in 1965 and 1970 respectively, both from the Indian Institute of Technology (IIT), Kharagpur, India. He is a pioneer in the area of system identification and during his career has held faculty positions at the Indian Institute of Technology Kharagpur, University of Manchester Institute of Science and Technology, Ruhr University Bochum, Fraunhofer Institute Berlin, University Henri Poincare, France, and Brunel University, UK. He has published over 150 papers and authored four books in the areas of system and control including the book Identification of Continuous Systems (with H. Unbehauen), North Holland, 1987. He currently serves as a member of the United Nations UNESCO Encyclopedia of Life Support Systems (EOLSS) joint committee. Professor Rao is a recipient of several recognitions including a Fellowship from Alexander von Humboldt Foundation, The Systems Society of India Award, International Desalination Association Best Paper Award and Honorary Professorship of the East China University of Science and Technology, Shanghai. He is a Life Fellow of the IEEE and a Fellow of the Indian National Academy of Engineering.
