Coherent Dynamics Enhanced by Uncorrelated Noise
Zachary G. Nicolaou, Michael Sebek, Istvan Z. Kiss +1
Synchronization is a widespread phenomenon observed in physical, biological, and social networks, which persists even under the influence of strong noise. Previous research on osci…
Robust Weak Chimeras in Oscillator Networks with Delayed Linear and Quadratic Interactions
Christian Bick, Michael Sebek, István Z. Kiss
We present an approach to generate chimera dynamics (localized frequency synchrony) in oscillator networks with two populations of (at least) two elements using a general method ba…
Stationary patterns in star networks of bistable units: Theory and application to chemical reactions
Nikos E Kouvaris, Michael Sebek, Albert Iribarne +2
We present theoretical and experimental studies on pattern formation with bistable dynamical units coupled in a star network configuration. By applying a localized perturbation to…
Self-Organized Stationary Patterns in Networks of Bistable Chemical Reactions
N. E. Kouvaris, M. Sebek, A. S. Mikhailov +1
Experiments with networks of discrete reactive bistable electrochemical elements organized in regular and nonregular tree networks are presented to confirm an alternative to the Tu…
On the necessity of symmetric positional coupling for string stability
Dan Martinec, Ivo Herman, Michael Šebek
We consider a distributed system with identical agents, constant-spacing policy and asymmetric bidirectional control, where the asymmetry is due to different controllers, which we…
Complex Rotating Waves and Long Transients in a Ring-Network of Electrochemical Oscillators with Sparse Random Cross-Connections
Michael Sebek, Ralf Tönjes, István Z. Kiss
We perform experiments and phase model simulations with a ring network of oscillatory electrochemical reactions to explore the effect of random connections and non-isochronocity of…
Transfer functions in consensus systems with higher-order dynamics and external inputs
Ivo Herman, Dan Martinec, Michael Sebek
This paper considers transfer functions in consensus systems where agents have identical SISO dynamics of arbitrary order. The interconnecting structure is a directed graph. The tr…
Scaling in bidirectional platoons with dynamic controllers and proportional asymmetry
Ivo Herman, Dan Martinec, Zdeněk Hurák +1
We consider platoons composed of identical vehicles with an asymmetric nearest-neighbor interaction. We restrict ourselves to intervehicular coupling realized with dynamic arbitrar…
A travelling wave approach to a multi-agent system with a path-graph topology
Dan Martinec, Ivo Herman, Michael Šebek
The paper presents a novel approach for the analysis and control of a multi-agent system with non-identical agents and a path-graph topology. With the help of irrational wave trans…
Nonzero bound on Fiedler eigenvalue causes exponential growth of H-infinity norm of vehicular platoon
Ivo Herman, Dan Martinec, Zdeněk Hurák +1
We consider platoons composed of identical vehicles and controlled in a distributed way, that is, each vehicle has its own onboard controller. The regulation errors in spacing to t…
Wave-absorbing vehicular platoon controller
Dan Martinec, Ivo Herman, Zdeněk Hurák +1
The paper tailors the so-called wave-based control popular in the field of flexible mechanical structures to the field of distributed control of vehicular platoons. The proposed so…
Plane geometry and convexity of polynomial stability regions
Didier Henrion, Michael Sebek
The set of controllers stabilizing a linear system is generally non-convex in the parameter space. In the case of two-parameter controller design (e.g. PI control or static output…
