Feedforward control of pantograph contact force based on phase-locked loop (Phase-locked loop for control force generation)

open access: yesNihon Kikai Gakkai ronbunshu, 2014
This paper proposes a feedforward controller for active suppression of contact force fluctuation between a pantograph and overhead contact line of a high-speed railway vehicle, assuming the use of a pneumatic actuator with low response speed.

Magnetic Control of Chiral Hybridized Phonon Magnetic Moments in Ferrimagnets Fe2‐xZnxMo3O8

open access: yesAdvanced Functional Materials, EarlyView.
Helicity‐resolved magneto‐Raman spectroscopy reveals magnetic control of chiral phonon magnetic moments in polar ferrimagnet (ZnxFe2−xMo3O₈). Large spontaneous zero‐field phonon splittings, selective phonon–magnon coupling, and asymmetric Zeeman responses demonstrate that phonon chirality is governed by magnon‐phonon coupling and magnetization.
