Electrical control of the linear optical properties of particulate composite materials [PDF]

open access: yes, 2006
The Bruggeman formalism for the homogenization of particulate composite materials is used to predict the effective permittivity dyadic of a two-constituent composite material with one constituent having the ability to display the Pockels effect ...

Robust Proportional–Integral Sliding Mode Control for Induction Motors with Input Time Delay

open access: yesEnergies, 2023
This paper proposes a control strategy applied to a three-phase induction motor (TIM) subject to parametric uncertainties, perturbations, and input time delay, whose primary objective is to achieve high-performance speed–torque control.

Direct Flux Field Oriented Control of IPM Drives with Variable DC-Link in the Field-Weakening Region [PDF]

open access: yes, 2009
This paper presents the direct flux control of an interior permanent-magnet (IPM) motor drive in the field-weakening region. The output torque is regulated by the coordinated control of the stator flux amplitude and the current component in quadrature ...

Waveform control of orientation-dependent ionization of DCl in few-cycle laser fields [PDF]

open access: yes, 2011
Strong few-cycle light fields with stable electric field waveforms allow controlling electrons on time scales down to the attosecond domain. We have studied the dissociative ionization of randomly oriented DCl in 5 fs light fields at 720 nm in the ...
