Implementation of Time-Varying Controllers for a Nonholonomic Mobile Robot: Experimental Studies
Alexander Zuyev, Victoria Grushkovskaya, Sebastian Eisner
We consider a kinematic model of a wheeled mobile robot controlled by translational and angular velocities. For this class of nonholonomic systems, a family of time-varying feedbac…
Model-free source seeking of exponentially convergent unicycle: theoretical and robotic experimental results
Rohan Palanikumar, Ahmed A. Elgohary, Victoria Grushkovskaya +1
This paper introduces a novel model-free, real-time unicycle-based source seeking design. This design autonomously steers the unicycle dynamic system towards the extremum point of…
A Model-Free Extremum Seeking Controller with Application to Tracking a Nonlinear Chemical Reaction
Alexander Zuyev, Victoria Grushkovska
In this paper, we develop the extremum-seeking approach to generate admissible trajectories in a neighborhood of a given reference curve in the state space. The cost function of th…
The Augmented Mixing Method: Computing High-Accuracy Primal-Dual Solutions to Large-Scale SDPs via Column Updates
Daniel Brosch, Jan Schwiddessen, Angelika Wiegele
The Burer-Monteiro factorization has become a powerful tool for solving large-scale semidefinite programs (SDPs), enabling recently developed low-rank solvers to tackle problems pr…
On classical solutions in the stabilization problem for nonholonomic control systems with time-varying feedback laws
Alexander Zuyev, Victoria Grushkovskaya
We consider the stabilization problem for driftless control-affine systems under the bracket-generating condition. In our previous works, a class of time-varying feedback laws has…
The exact subgraph hierarchy and its vertex-transitive variant for the stable set problem for Paley graphs
Elisabeth Gaar, Dunja Pucher
The stability number of a graph, defined as the cardinality of the largest set of pairwise non-adjacent vertices, is NP-hard to compute. The exact subgraph hierarchy (ESH) provides…
