SUMMARY:Vortrag von Prof. Peter Seiler
DESCRIPTION:Prof. Peter Seiler\nElectrical Engineering and Computer Science\nUniversity of Michigan\nAnn Arbor, MI, USA\n\n\n  \nFriday 2024-05-17 11:00 a.m.\nIST Seminar Room 2.255 - Pfaffenwaldring 9 - Campus Stuttgart-Vaihingen  \nAbstract\nThis talk will consider robust disturbance rejection in high precision applications. We will\nstart by motivating the work with one relevant problem: the control required for optical\ncommunication between satellites.  We will then discuss the fundamental performance limits\nassociated with linear time invariant (LTI) control. Linear time varying controllers, e.g. those\nthat rely on online convex optimization, can potentially provide significant performance\nimprovements. However, the ability to accurately adapt to the disturbance while maintaining\nclosed-loop stability relies on having an accurate model of the plant. In fact, the model\nuncertainty can cause the closed-loop to become unstable. We provide a sufficient condition for\nrobust stability based on the small gain theorem using the ell-infinity norm. This condition is\neasily incorporated as an on-line constraint in controllers that rely on online convex\noptimization.  \nBiographical Information\nPeter Seiler is an Associate Professor in Electrical Engineering and Computer Science at the\nUniversity of Michigan. He is an IEEE Fellow and the recipient of the O. Hugo Schuck Award (2003)\nand an NSF CAREER award (2013). His research focuses on robust control theory which addresses the\nimpact of model uncertainty on systems design. He has been a contributor to the Robust Control\nToolbox in Matlab since 2001. He was a Principal Scientist from 2004-2008 in the Aerospace\nElectronic Systems group at the Honeywell Labs. During that time, he worked on the redundancy\nmanagement system for the Boeing 787, sensor fusion algorithms for automotive active safety\nsystems, and re-entry flight control laws for NASA  s Orion vehicle.  \n
