SUMMARY:Vortrag von Prof. Leonid Mirkin
DESCRIPTION:Prof. Leonid Mirkin\nFaculty of Mechanical Engineering\nTechnion - Israel Institute of Technology\nHaifa, Israel  \nTuesday, 2017-04-11 16:00\n IST-Seminar-Room V9.22 - Pfaffenwaldring 9 - Campus Stuttgart-Vaihingen  \nAbstract  \nThe appeal of event-triggered control is its potential ability to outperform conventional\n(time-triggered) sampled-data systems under comparable communication demands. A striking example of\nthis ability is the Lebesgue sampling algorithm of Åström & Bernhardsson (1999), proposed for\nthe minimum-variance control of first-order analog plants with impulsive control action and\nnoiseless measurements of the plant state. In the case of a single integrator, the algorithm\noutperforms the optimal time-triggered sampled-data controller, under the same average sampling\nrate, by a factor of 3. However, extending this result to more general / practical settings has\nproven to be a challenge.\nIn this talk, I will present an approach to the minimum-variance event-triggered control in a\ngeneral "standard problem" setting. The main result is a full separation between the controller\narchitecture and event-triggering mechanism, which, in turn, reduces the problem to an optimal\nstopping problem for a Markov process driven by a white input. I will discuss implications of this\nfor some special cases (like the overall optimality of the scheme of Åström & Bernhardsson and\nits extendibility to systems with measurement noise and limited control effort).\nThis is a joint work with Alexander Goldenshluger from U Haifa. Remarkably, this collaboration\non stochastic event-triggered control was triggered by two deterministic events that took place in\nthe city of Frunze in mid-late '60s.  \n   \n  \nBiographical Information  \nLeonid Mirkin is a native of Frunze, Kirghiz SSR, USSR (now Bishkek, Kyrgyz Republic). He\nreceived the Electrical Engineer degree from Frunze Polytechnic Institute and the PhD (candidate of\nsciences) degree in automatic control from the Institute of Automation, Academy of Sciences of\nKyrgyz Republic, in 1989 and 1992, respectively. He joined the Faculty of Mechanical Engineering at\nthe Technion - Israel Institute of Technology in 1994, first as a postdoc and then as a faculty.\nHis research interests include systems theory, control and estimation of sampled-data systems,\ndead-time compensation, systems with preview, distributed control, and applications in\nelectro-mechanical systems and process control.  \n    \n\n
