Title "Time delay algorithms for vibration suppression, from input-shaping to active multi-dimensional absorbers"

＜Abstract＞
Incorporating time delays into control algorithms has proven useful in many aspects of vibration suppression and flexible mode compensation of mechanical systems. This is mainly due to the ability of time delays to store information about the current half-period and act proportionally in the subsequent half-period, or its multiples, to counteract vibration. On the other hand, introducing time delays into the feedback loop results in a closed-loop system with infinitely many poles.
After highlighting the spectral properties of delay systems and controllers, as well as their frequency-domain implications for vibration suppression, several methods will be discussed. These include flexible mode compensation using input shaping and nonlinear controllers, repetitive control, and vibration absorption employing non-collocated or multi-dimensional absorbers. For all these methods, either laboratory or industrial validation will be presented.

＜Biography＞
Tomáš Vyhlídal received his Ph.D. in Control and Systems Engineering in 2003 from the Faculty of Mechanical Engineering (FME) at the Czech Technical University in Prague (CTU). In 2012, he was appointed Professor at CTU. Since 2000, he has been with the Department of Instrumentation and Control Engineering at FME-CTU, where he has served as Head of the Department since 2019. Since 2015, he has also been affiliated with the Czech Institute of Informatics, Robotics and Cybernetics (CIIRC) at CTU. His research interests include the analysis and control of time-delay systems, mathematical modelling, and applied control theory. He has coordinated several projects focusing on the application of time-delay algorithms for flexible mode compensation and vibration suppression. Currently, he serves as a Research Area Leader in the ROBOPROX.EU project, focusing on the control of distributed-parameter systems and complex robotic structures. Since 2013, he has been a member of the IFAC Technical Committee on Linear Control Systems, serving as Vice-Chair for Industry from 2017 to 2023.
