Time-delayed feedback control of diffusion in random walkers

2017-07-25T10:00:00-04:00

Author(s): Hiroyasu Ando, Kohta Takehara, and Miki U. Kobayashi
Time delay in general leads to instability in some systems, while specific feedback with delay can control fluctuated motion in nonlinear deterministic systems to a stable state. In this paper, we consider a stochastic process, i.e., a random walk, and observe its diffusion phenomenon with time-dela...
