Lennart Ljung is a Swedish professor in the Chair of Control Theory at Linköping University since 1976. He is known for his pioneering research in system identification, and is regarded as a leading researcher in control theory.[1] [2] [3]
Lennart Ljung received the B.A. in Russian Language and Mathematics 1967, the M.Sc. (first degree) in Engineering Physics 1970, and the Ph.D.[4] in Control Theory 1974, all from Lund University.
Following a position as a research associate at Stanford University 1974–1975 and a position as an associate professor (docent) in control theory at Lund University in 1975–1976, Lennart Ljung was elected as a professor in the chair of control theory at Linköping University in 1976. He was a visiting researcher at Stanford University 1980–1981 and at Massachusetts Institute of Technology 1985–1986. He was also Department Head of the Department of Electrical Engineering, Linköping University between 1981 and 1990. He is currently the Director of the MOVIII Strategic Research Center at Linköping University. He has made extensive contributions to control theory, particularly in the area of system identification. He has authored 10 books, over 150 international journal articles, over 200 international conference papers, and a widely used commercial software package for MATLAB called the System Identification Toolbox.[5]
Lennart Ljung is ranked 84 in the world (1st within Sweden) in the field of Engineering and Technology.[6]
