Nonlinear Control of Delay and PDE Systems: Methods and Applications

Back
Abstract:
Delay and PDE systems are ubiquitous in applications. The distributed nature of such processes create challenges in control. I will present my recent results on the nonlinear control of delay systems with nonconstant delays and on the nonlinear control of coupled ODE and PDE systems, using the concepts of nonlinear predictor feedback and infinite-dimensional backstepping-forwarding transformation. I will explain how the control and analysis tools, that I have developed, can be applied to three major technological problems--3D printing, oil drilling, and human occupancy estimation. I will conclude by addressing some additional potential future research areas.

Biographical Sketch:
Nikolaos Bekiaris-Liberis is currently a postdoctoral researcher at the University of California, Berkeley. He obtained his PhD degree from the University of California, San Diego in June 2013. He has coauthored the SIAM book "Nonlinear Control under Nonconstant Delays." Bekiaris-Liberis was finalist for the student best paper award at the 2010 ASME Dynamic Systems and Control Conference, and at the 2013 IEEE Conference on Decision and Control. He taught tutorials on control of nonlinear delay systems at the 2012 IEEE Conference on Decision and Control and within the European Embedded Control Institute in 2013. His interests are in delay systems, distributed parameter systems, nonlinear control, and their applications.
