Multistackable, Domino‐Overlapped CNT Scaffolds Homogeneously Hybridized with BTO‐P(VDF‐TrFE) for High‐Performance Piezoelectric Nanogenerators

open access: yesAdvanced Functional Materials, EarlyView.
A multilayer‐stackable carbon nanotuber (CNT) scaffold‐based piezoelectric nanogenerator (CPENG) with domino‐patterned CNT pillars presents high, stable output (12.3 V, size of 1 cm × 1 cm) over 2000 cycles, operates across a wide temperature range, and efficiently converts energy from real‐life stimuli through optimized CNT length, layer stacking, and

Teaching Field Oriented Control using Animation

2021 17th Conference on Electrical Machines, Drives and Power Systems (ELMA), 2021
Teaching the principles of control of electrical machines is a tedious job. Especially the required knowledge that has to be transmitted to the student is large, before a complete overview of the whole topic can be made. Also a solid background in both electrical machine dynamic behavior as well as in control theory is required for the student, before ...

The universal field oriented controller

IEEE Transactions on Industry Applications, 1994
This paper synthesizes and develops a universal field oriented (UFO) controller for induction machines. The UFO controller decouples flux and torque in an arbitrary flux reference frame. Due to its high degree of generality the UFO controller lends itself to be fully compatible with all existing field oriented controllers, indirect as well as direct ...

SERVICE-ORIENTED ARCHITECTURE FOR FIELD CONTROL DEVICES

IFAC Proceedings Volumes, 2006
Abstract The concept of Service-Oriented Architecture has become more and more important in the last few years in several technological fields and is beginning to play an important role also in the industrial automation field. The paper presents the application of this paradigm to field control devices of a flexible manufacturing system.
