报告题目：Iterative Learning Control (ILC) for the Class of Spatially Distributed Systems
内容简介：In this lecture, a robust control design is presented for an electrostatic microbridge actuator. For this system, a spatially distributed electrostatic force serves as control input. Moreover, a spatially distributed measurement of the bridge displacement is assumed to be available. For an accurate tracking of a reference trajectory—repeated periodically during the operation of the microbridge—an iterative learning control (ILC) approach is proposed based on so-called wave repetitive processes. The design procedure represents an efficient combination of linear matrix inequalities and an appropriate parameter optimization. By explicitly considering polytopic parameter uncertainty, the ILC becomes robust against uncertain parameters such as the squeeze film damping coefficient, the mass density, and the time constant of the electrostatic actuator. Convincing simulation results provide a numerical validation of the proposed ILC scheme as a prestage for a future experimental implementation.
报告人简介：Dr. Krzysztof Galkowski received his Ph.D. degrees from Technical University of Wroclaw in 1977. After a twenty-year stint at the University of Wroclaw, he joined the University of Zielona Gora in 1996, where he is currently a Professor of Institute of Control and Computation Engineering. Professor Galkowski is an inventor of the effective and still being generalised by other researchers, method of the construction of a state-space realization for the multidimensional (n-variate) transfer function matrices, called Elementary Operation Algorithm. His research interests include multidimensional (nD) systems and repetitive processes-theory and applications, Iterative Learning Control and related numerical methods. He is an author/editor of four monographs/books and over 100 papers in the leading peer reviewed journals and over 180 in the proceedings of international conferences. He has given numerous invited plenary talks for international conferences and in many universities (Europe, USA, Canada, China, Australia, India). He, as well, has prepared numerous special issues for leading journals as IJC, MDSSP and others. He has a strong international co-operation with the Universities of Southampton, UK; the universities of Wuppertal, Rostock and Erlangen-Nurnberg, Germany; University of Hong Kong; University of Poitiers, France; University of Thessaloniki, Greece; East China University of Science and Technology, Shanghai; Harbin Institute of Technology, Harbin; Central South University, Changsha; China University of Geosciences, Wuhan, and many others.
Dr. Krzysztof Galkowski is an associate editor for IET Control Theory and Applications, and a member of editorial board of International Journal of Multidimensional Systems and Signal Processing and International Journal of Control. He served as a member of IPC for several international conferences and co-organized a series of international workshops.
