Open Problems on Information and Feedback Controlled Systems
F. J. Cao, M. Feito
Feedback or closed-loop control allows dynamical systems to increase their performance up to a limit imposed by the second law of thermodynamics. It is expected that within this li…
Optimal operation of feedback flashing ratchets
M. Feito, F. J. Cao
Feedback flashing ratchets are thermal rectifiers that use information on the state of the system to operate the switching on and off a periodic potential. We discuss different str…
Thermodynamics of feedback controlled systems
F. J. Cao, M. Feito
We compute the entropy reduction in feedback controlled systems due to the repeated operation of the controller. This was the lacking ingredient to establish the thermodynamics of…
Transport reversal in a delayed feedback ratchet
M. Feito, F. J. Cao
Feedback flashing ratchets are thermal rectifiers that use information on the state of the system to operate the switching on and off of a periodic potential. They can induce direc…
Flux enhancement and multistability induced by time delays in a feedback controlled flashing ratchet
F. J. Cao, M. Feito
Feedback controlled ratchets are thermal rectifiers that use information on the state of the system to operate. We study the effects of time delays in the feedback for a protocol t…
Time-Delayed Feedback control of a flashing ratchet
M. Feito, F. J. Cao
Closed-loop or feedback control ratchets use information about the state of the system to operate with the aim of maximizing the performance of the system. In this paper we investi…
