Adaptive Vibration Suppression System: An Iterative Control Law for a Piezoelectric Actuator Shunted by a Negative Capacitor

Tomas Sluka, Pavel Mokry

An adaptive system for the suppression of vibration transmission using a single piezoelectric actuator shunted by a negative capacitance circuit is presented. It is known that by using a negative-capacitance shunt, the spring constant of a piezoelectric ac ...

Multivariable-PI-based DQ Current Control of Voltage Source Converters with Superior Axes Decoupling Capability

Alfred Rufer, Behrooz Bahrani, Stephan Kenzelmann

This paper presents a linear direct-quadrature (dq) current control strategy for voltage source converters (VSCs) in a rotating reference frame (RRF). The described method is based on Multivariable proportional-integral (PI) regulators and provides fast dy ...

Magnetoelectricity in the ferrimagnetic Cu2OSeO3: symmetry analysis and Raman scattering study

Helmuth Berger

sublattices ferrimagnet Cu2OSeO3 with a cubic symmetry and a linear magnetoelectric effect. There is no spectroscopic evidence for structural lattice distortions below T-C=60 K, which are expected due to magnetoelectric coupling. Using symmetry arguments w ...

Subcoercive cyclic electrical loading of lead zirconate titanate ceramics I: nonlinearities and losses in the converse piezoelectric effect

Dragan Damjanovic

The converse piezoelectric response of Pb(ZrxTi1−x)O3 ceramics is investigated as a function of material composition. The effects of the crystallographic phase and different dopants on piezoelectric nonlinearity are separately examined. For a linear depend ...

Design of an integrated low-noise read-out system for DNA capacitive sensors

Sandro Carrara, Daniela De Venuto

This paper presents an electronic system for a fast DNA label-less detection. The sensitivity of the capacitive sensor in use is improved by depositing an insulating self-assembled monolayer (SAM) over the golden electrodes. The capacitance shift due to th ...
