In last month, professor Christian Ebenbauer visited CDSL for the guest lecture under the theme “Lie Brackets and Extremum Seeking Control”. In the lecture conducted for about six hours on three occasions, professor Ebenbauer introduced the physical meaning, mathematical characteristics, and application in control systems of Lie brackets.
Professor Ebenbauer emphasized the importance of ‘Lie brackets’ in the analysis of ‘controllability’ for non-holonomic systems. The sequential application of high-frequency sinusoidal input into the system results in a new direction of control input, which gives an approximation to an arbitrary path.
He also explained how these approximate path-generation methods could effectively solve the extremum seeking control problem. The reason why the proposed method is so valuable in research is that only the system’s output is necessary for implementation of the method and no other information is required.
Control and Dynamic Systems Laboratory (CDSL) has been giving guest lectures of distinguished scholars majoring in control theory. Professor Shim, head of CDSL, said, “We will continue to invite remarkable researchers and make every effort to create a place for meeting and discussion with students so that they can conduct enterprising research.”
Meanwhile, professor Jungsu Kim (from SEOULTECH) and professor Hongkeun Kim (from KOREATECH) participated in the seminar.
