FPGA implementation of adaptive sliding mode control and genetically optimized PID control for fractional-order induction motor system with uncertain load

open access: yesAdvances in Difference Equations, 2017
In this paper, we investigate the control of 4-D nonautonomous fractional-order uncertain model of a PI speed-regulated current-driven induction motor (FOIM) using a fractional-order adaptive sliding mode controller (FOASMC).

Different Facets of Chaos in Quantum Mechanics

open access: yes, 1999
Nowadays there is no universally accepted definition of quantum chaos. In this paper we review and critically discuss different approaches to the subject, such as Quantum Chaology and the Random Matrix Theory.

Suppression of Chaos in a One-dimensional Mapping [PDF]

open access: yesJournal of Biological Physics, 1997
The suppression of chaos in an one-dimensional model of malignant tumor growth is presented. As a result, a steady-state and differentperiodic motions, embedded in the chaotic attractor, arestabilized.

Chaos Suppression in Fractional order Permanent Magnet Synchronous Generator in Wind Turbine Systems

open access: yesNonlinear Engineering, 2017
In this paper we investigate the control of three-dimensional non-autonomous fractional-order uncertain model of a permanent magnet synchronous generator (PMSG) via a adaptive control technique.

Finite-Time Chaos Suppression of Permanent Magnet Synchronous Motor Systems

open access: yesEntropy, 2014
This paper considers the problem of the chaos suppression for the Permanent Magnet Synchronous Motor (PMSM) system via the finite-time control. Based on Lyapunov stability theory and the finite-time controller are developed such that the chaos behaviors ...

Particle Motion and Chaos

open access: yesAdvances in High Energy Physics, 2020
In this note, we consider particle falling in the black hole with an additional potential. Following the proposal by Susskind (2018), we study the growth rate of the particle’s Rindler momentum, which corresponds to the growth rate of the operator size ...

Non-monotonicity in the quantum-classical transition: Chaos induced by quantum effects [PDF]

open access: yes, 2007
The transition from classical to quantum behavior for chaotic systems is understood to be accompanied by the suppression of chaotic effects as the relative size of $\hbar$ is increased.

Suppression of chaos at slow variables by rapidly mixing fast dynamics through linear energy-preserving coupling

open access: yes, 2011
Chaotic multiscale dynamical systems are common in many areas of science, one of the examples being the interaction of the low-frequency dynamics in the atmosphere with the fast turbulent weather dynamics.

Chaos and high temperature pure state thermalization

open access: yesJournal of High Energy Physics, 2019
Classical arguments for thermalization of isolated systems do not apply in a straightforward way to the quantum case. Recently, there has been interest in diagnostics of quantum chaos in many-body systems.
