Optimal Control for Steady Circulation of a Diffusion Process via Spectral Decomposition of Fokker-Planck Equation

Norihisa Namura, Hiroya Nakao

We present a formulation of an optimal control problem for a two-dimensional diffusion process governed by a Fokker-Planck equation to achieve a nonequilibrium steady state with a…

Optimal interaction functions realizing higher-order Kuramoto dynamics with arbitrary limit-cycle oscillators

Norihisa Namura, Riccardo Muolo, Hiroya Nakao

The Kuramoto model is the simplest case of globally coupled phase oscillators with a purely sinusoidal fundamental-harmonic phase coupling function, whose dynamical properties have…

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…

A Central Pattern Generator Network for Simple Control of Gait Transitions in Hexapod Robots based on Phase Reduction

Norihisa Namura, Hiroya Nakao

We present a model of the central pattern generator (CPG) network that can control gait transitions in hexapod robots in a simple manner based on phase reduction. The CPG network c…

Optimal coupling functions for fast and global synchronization of weakly coupled limit-cycle oscillators

Norihisa Namura, Hiroya Nakao

We propose a method for optimizing mutual coupling functions to achieve fast and global synchronization between a pair of weakly coupled limit-cycle oscillators. Our method is base…

Estimating asymptotic phase and amplitude functions of limit-cycle oscillators from time series data

Norihisa Namura, Shohei Takata, Katsunori Yamaguchi +2

We propose a method for estimating the asymptotic phase and amplitude functions of limit-cycle oscillators using observed time series data without prior knowledge of their dynamica…
