SUMMARY:Vortrag von Dr. ir. Roland Toth
DESCRIPTION:Dr. ir.Roland Toth\nAssociate Professor\nControl Systems Group\nDepartment of Electrical Engineering\nEindhoven University of Technology, The Netherlands\n  \nTuesday 2020-01-14 16:00\nIST-Seminar-Room V9.2.255 - Pfaffenwaldring 9 - Campus Stuttgart-Vaihingen\nAbstract\nThe Linear Parameter-Varying (LPV) framework has been introduced with the intention to provide\nstability and performance guarantees for analysis and controller synthesis for Nonlinear (NL)\nsystems via convex methods. By extending results of the LTI framework, it was assumed that they\ngeneralize tracking and disturbance rejection guarantees for NL systems. But as we show, such\nguarantees are not true in general. We propose to solve this problem by the application of\nincremental stability and performance, which does indeed ensure these specifications. In this talk,\nan overview of the theoretical results is given and stability and performance notions related to\nincremental stability and dissipativity are presented. Based on these results, a novel approach is\nproposed to synthesize and realize an LPV controller which is able to guarantee incremental\nstability and performance for NL systems via convex optimization. Through examples, the presented\nmethod is compared to standard L2 gain optimal LPV controller design, showing significant\nperformance improvements. Finally, the approach is experimentally verified on an unbalanced disc\nsetup, displaying the shortcomings of standard L2 gain optimal LPV controllers. \nBiographical Information\nRoland Tóth obtained his BSc in Electrical Engineering and MSc degree in Information Technology\ncum laude from the University of Pannonia (Hungary) in 2004. In 2008, he completed his PhD in\nControl Engineering at the Delft University of Technology (TU Delft), also cum laude. From 2008 to\n2010, Tóth worked as a postdoctoral researcher at TU Delft while also working on a research project\nfor Philips Apptech. In 2010, he joined the University of California (USA) for a postdoc project,\nbefore returning to the Netherlands in 2011 to become Assistant Professor at TU Delft. Tóth joined\nEindhoven University of Technology as Assistant Professor in 2012 and was promoted to Associate\nProfessor in 2018. His research interests are in linear parameter-varying (LPV) and nonlinear\nsystem identification and control, machine learning for modelling and control, model predictive\ncontrol and behavioral system theory. Dr. Tóth received the TUDelft Young Researcher Fellowship\nAward in 2010, the VENI award of The Netherlands Organisation for Scientific Research in 2011 and\nthe Starting Grant of the European Research Council in 2016.
