Applying the voltage-mode hysteretic control to multiphase Voltage Regulator Modules (VRMs) can satisfy many of the new and future generation of microprocessors and ICs powering requirements. This is because of the numerous advantages that can be obtained when both techniques are used. However, several challenges arise that include current sharing, multiphase control signals distribution, high-...

A big problem in many technical applications is the complex hysteretic characteristic of sensors and actuators, which causes a non-linear and multi-valued mapping between the output variable and the input variable of the transducer. In the last few years at the LPA a general modeling and compensator design method was developed for such complex hysteretic nonlinearities which is based on the so-...

The low temperature monoclinic, insulating phase of vanadium dioxide is ordinarily considered nonmagnetic, with dimerized atoms forming spin singlets, though paramagnetic response seen at temperatures. We find a nonlocal Seebeck signal in VO2 films that appears below 30 K and which increases decreasing temperature. has non-hysteretic dependence on in-plane external magnetic field. This discusse...

Hysteresis is a common phenomenon in various non linear systems including piezoceramic materials. Piezoelectric bimorph devices show hysteretic behaviour, when operating as actuators. In this paper an experimental set-up to investigate the hysteretic behaviour of a PZT is described. The strategy adopted uses a resistive readout scheme and a CCD tool for the system calibration. Moreover, softwar...

Piezoelectric, magnetostrictive, and shape memory alloy actuators are gaining importance in high-frequency precision applications constrained by space. Their intrinsic hysteretic behavior makes control difficult. The Prandtl–Ishlinskii (PI) operator can model hysteresis well, albeit a major inadequacy: the inverse operator does not exist when the hysteretic curve gradient is not positive defini...

Time history response analyses of horizontal hybrid wooden structures with RC core on one or both sides are conducted considering the elasto-plasticity part Wayne-Stewart model as hysteretic characteristics. Then, by comparing results static analyses, effects amplification and eccentricity verified, consistency load-carrying capacity calculation, such setting structural characteristics factor D...

This paper aims to study the efficiency of energy dissipators, both fluid viscous and hysteretic, improve seismic responses buildings. To quantify ability dissipators reduce responses, a series time history analyzes were carried out on simplified models Said consist masses springs with linear elastic behavior whose properties are obtained from shear beam model, joined by link elements non-linea...
