Electric-field control of tri-state phase transformation with a selective dual-ion switch

Field Oriented Control of Dual Mechanical Port Machine for Hybrid Electric Vehicle

A dual mechanical port machine (DMPM) is used as an electrically variable transmission (EVT) in hybrid electric vehicle (HEV). In the conventional HEV, this machine is replaced by a planetary gearbox and two electric machines and makes this structure simpler. This paper presents field oriented control (FOC) for DMPM. For HEV application, drive efficiency and wide operating speed range are impor...

Electric-Field Control of a Magnetic Phase Transition in Ni3V2O8

We report on the electric-field tuning of a magnetic phase transition temperature (TL) in multiferroic Ni3V2O8 thin films. The simultaneous magnetic and ferroelectric transition in Ni3V2O8 exhibits a clear dielectric anomaly; we monitored TL under applied electric and magnetic fields using dielectric measurements. The transition temperature increases by 0.2 K±0.05 K when the sample is biased ap...

An Improved Control Approach for Dual Mechanical Coupled BLDC Motor With Nine-Switch Inverter

This paper presents the control approach for single inverter dual coupled brushless DC motors (DCBLDC) drive system. One of the basic requirements of such systems, is the power balance between two motors and on the other hand, minimizing mechanical fluctuations in order to avoid mechanical equipment damage especially in the state of mechanical resonance. This paper also presents an improved for...

Phase-field model for solid state transformation in a two-phase binary system with elastic inhomogeneity

A phase-field model is presented to study binary systems having two phases with different elastic properties. The evolution of two phase-field variables, namely, composition and non-conserved phase-field, are considered. This model uses the approach of Steinbach and Apel [1] to model the dependence of total strain on the phase-field, which assumes equal elastic stresses in the different phases ...
