Averaging of Random Vibrations in Mechanical Systems in the Sense of Ito, Stratonovich, and Sussmann

Raik Suttner, Christian Ebenbauer

In this paper, we investigate a stochastic averaging principle for a large class of mechanical systems in the presence of random vibrations. We show that a known deterministic aver…

Global exponential stabilization of a force- and torque-actuated unicycle by flexible-step MPC

Ala Kolsi, Christian Ebenbauer, Bahman Gharesifard +1

We study the problem of global exponential stabilization of a force- and torque-controlled unicycle model in discrete time. To this end, we extend a recently introduced approach to…

Extremum Seeking with Double Integrators in the Presence of Local Extrema

Raik Suttner, Christian Ebenbauer, Sergey Dashkovskiy

We study the problem of global extremum seeking in the presence of local extrema. We investigate two different perturbation-based methods: 1) a well-known classical extremum seekin…

Non-Local Extremum Seeking Based on the Divergence Theorem

Raik Suttner, Christian Ebenbauer, Sergey Dashkovskiy

We propose a new design strategy for extremum seeking control for a multi-dimensional single-integrator system in the presence of local extrema. The proposed method employs suitabl…

Flexible-step MPC for Unknown Linear Time-Invariant Systems

Markus Pietschner, Christian Ebenbauer, Bahman Gharesifard +1

We propose a novel flexible-step model predictive control algorithm for unknown linear time-invariant discrete-time systems. The goal is to asymptotically stabilize the system with…

Nonlocal Nonholonomic Source Seeking Despite Local Extrema

Raik Suttner, Miroslav Krstic

In this paper, we investigate the problem of source seeking with a unicycle in the presence of local extrema. Our study is motivated by the fact that most of the existing source se…
