Global Phase Synchronization Decoupled from Amplitude Dynamics

Koichiro Yawata, Hiroya Nakao

The Kuramoto model is a canonical framework for analyzing phase synchronization, yet its utility is restricted to the vicinity of the oscillator's unperturbed limit cycle. Here, we…

Data-driven phase control for limit-cycle oscillators under partial observation

Koichiro Yawata, Norihisa Namura, Yuzuru Kato +1

Controlling rhythmic systems, typically modeled as limit-cycle oscillators, is an important subject in real-world problems. Phase reduction theory, which simplifies the multidimens…
