Learning dynamic control of body yaw orientation

VP Vimal, JR Lackner, P DiZio - Experimental brain research, 2018 - Springer
To investigate the role of gravitational cues in the learning of a dynamic balancing task, we
placed blindfolded subjects in a device programmed with inverted pendulum dynamics …

Delay, resonance and the Lambert W function

K Ohira, T Ohira - arXiv preprint arXiv:2301.13448, 2023 - arxiv.org
We discuss a new type of delay differential equation that exhibits resonating transient
oscillations. The power spectrum peak of the dynamical trajectory reaches its maximum …

Semi-discretization and the time-delayed PDA feedback control of human balance

T Insperger, J Milton, G Stepan - IFAC-PapersOnLine, 2015 - Elsevier
An important question for human balance control concerns how the differential equations for
the neural control of balance should be formulated. In this paper, we consider a discrete …

Delayed Dynamics with Transient Resonating Oscillations

K Ohira, T Ohira - Journal of the Physical Society of Japan, 2023 - journals.jps.jp
Recently, we have studied a delay differential equation which has a coefficient that is a
linear function of time. The equation has shown the oscillatory transient dynamics appear …

Prehension of half-full and half-empty glasses: time and history effects on multi-digit coordination

Y Sun, VM Zatsiorsky, ML Latash - Experimental brain research, 2011 - Springer
We explored how digit forces and indices of digit coordination depend on the history of
getting to a particular set of task parameters during static prehension tasks. The participants …

zones for position and velocity perception using a special combination of delayed state …

On the dimension reduction of systems with feedback delay by act-and-wait control

T Insperger, G Stepan - IMA Journal of Mathematical Control …, 2010 - academic.oup.com
Dimension reduction properties of the act-and-wait controller for systems with feedback
delay are analysed. The point of the act-and-wait concept is that the feedback is switched on …
