Advances in Electroactive Liquid Crystal Elastomers for Intelligent Robotics and Electronics

open access: yesAdvanced Robotics Research, EarlyView.
Electroactive liquid crystal elastomers (eLCEs) integrate molecular anisotropy with electrical functionality to enable programmable actuation and reconfigurable electronics. This review classifies eLCEs into robotic actuators and adaptive electronics, summarizes key actuation mechanisms, and highlights fabrication strategies that bridge materials to ...

New torque and flux controllers for direct torque control of induction machines

The Fifth International Conference on Power Electronics and Drive Systems, 2003. PEDS 2003., 2004
This paper presents the implementation of a high performance direct torque control (DTC) of induction machines drive. DTC has two major problems, namely, high torque ripple and variable switching frequency. In order to solve these problems, this paper proposed a pair of torque and flux controllers to replace the hysteresis-based controllers. The design

Automatic Torque Controller for Torque Motors

Journal of the Society of Motion Picture and Television Engineers, 1952
The use of the automatic torque controller permits the full advantages of torque motors to be realized for film take-up and holdback duty without being handicapped by their inherent limitations when operated in the conventional manner.
