IJICIC, Vol.5, No.9, (2009), pp.2809-2818      Sep 2009
We investigate bifurcation phenomena between slow and fast convergences of
synchronization errors arising in the proposed synchronization system
consisting of two identical nonlinear dynamical systems linked by a common
noisy input only. The numer...

Coupled human balancing tasks are investigated based on both pseudo-neural
controllers characterized by time-delayed feedback with random gain and natural
human balancing tasks. It is shown numerically that, compared to single
balancing tasks, bal...

A coupled inverted pendula model of competition and cooperation is proposed to obtain a purely mechanical implementation of dynamics comparable with the Lotka-Volterra competition dynamics. It is shown numerically that the proposed model can produ...

力学系とその複製に共通のランダム外乱を加えると,両者の応答が同期する現象がある.このような同期状態への収束性の悪化を,統計的等価線形法を用いて定量的に特徴づけた.収束性が悪化する条件では非定常確率密度関数が多峰性を示すことを見出し,この多峰性を検出する手法として積率微分方程式を用いた.積率の周波数応答曲線と同期の平均収束時間を比較したところ,積率の跳躍点と収束性の悪化する条件がよく対応した.

The paper studies how to switch equilibriums of a nonlinear dynamical system by human manipulation. We first develop a bang-bang control technique to switch the equilibriums. Then, we perform an experiment in which human subjects manually produce ...
