Stabilization of a chaotic oscillator via a class of integral controllers under input saturation

R Aguilar-López, JL Mata-Machuca - Scientific Reports, 2023 - nature.com
This work presents the straightforward design of an integral controller with an anti-windup
structure to prevent undesirable behavior when actuator saturation is considered, and the …

Rare-reversal chaos in two-disk dynamo models

P Frick, R Pleshkov - Physical Review E, 2024 - APS
A systematic comparative study of two-disk dynamo models without friction (the Rikitake
model) and with friction has been carried out. It is shown that the sets of chaotic and periodic …

Insights into pre-reversal paleosecular variation from stochastic models

K Peqini, B Duka, A De Santis - Frontiers in Earth Science, 2015 - frontiersin.org
To provide insights on the paleosecular variation of the geomagnetic field and the
mechanism of reversals, long time series of the dipolar magnetic moment are generated by …
