Local perturbations of generalized systems under feedback and derivative feedback

Local perturbations of generalized systems under feedback and derivative feedback

Following V.I. Arnolds techniques, we construct a local canonical form called miniversal deformation, for a family of differentiable regularizable linear dynamical systems Eẋ(t) = Ax(t)+Bu(t) under feedback and derivative feedback equivalence. We show some applications to the analysis of perturbations of a given regularizable system. c © 2008 Elsevier Ltd. All rights reserved.

Generalized Jarzynski equality under nonequilibrium feedback control.

The Jarzynski equality is generalized to situations in which nonequilibrium systems are subject to a feedback control. The new terms that arise as a consequence of the feedback describe the mutual information content obtained by measurement and the efficacy of the feedback control. Our results lead to a generalized fluctuation-dissipation theorem that reflects the readout information, and they ...

Partial Eigenvalue Assignment in Discrete-time Descriptor Systems via Derivative State Feedback

A method for solving the descriptor discrete-time linear system is focused. For easily, it is converted to a standard discrete-time linear system by the definition of a derivative state feedback. Then partial eigenvalue assignment is used for obtaining state feedback and solving the standard system. In partial eigenvalue assignment, just a part of the open loop spectrum of the standard linear s...
