The Small-Talk Effect in Practical Synchronization of Heterogeneous Oscillating Dynamics
Finn Voland, Vincent Schmidtke, Zonglin Liu +1
This paper investigates multi-time scale commu- nication schemes in synchronization of heterogeneous Lienard oscillator systems. Existing results rely on global exchange of informa…
Contraction Analysis of Filippov Solutions in Multi-Modal Piecewise Smooth Systems
Zonglin Liu, Kyra Borchhardt, Olaf Stursberg
This paper provides conditions to ensure contractive behavior of Filippov solutions generated by multi-modal piecewise smooth (PWS) systems. These conditions are instrumental in an…
Using Seminorms To Analyze Contraction of Switched Systems With Only Non-Contracting Modes
Edwin Baum, Zonglin Liu, Yuzhen Qin +1
This paper investigates contraction properties of switched dynamical systems for the case that all modes are non-contracting, thereby extending existing results that require at lea…
Control of Discrete-Time Linear Systems with Charge-Balanced Inputs
Yuzhen Qin, Zonglin Liu, Marcel van Gerven
Electrical brain stimulation relies on externally applied currents to modulate neural activity, but safety constraints require each stimulation cycle to be charge-balanced, enforci…
On Optimal Synchronization of Diffusively Coupled Heterogeneous Van der Pol Oscillators
Tabea Trummel, Zonglin Liu, Olaf Stursberg
This paper proposes a novel method to achieve and preserve synchronization for a set of connected heterogeneous Van der Pol oscillators. Unlike the state-of-the-art synchronization…
