Direct instantaneous torque control with wide operating range for switched reluctance motors
IET Electric Power Applications, 2015 Owing to the constraint of the supply voltage, there is a theoretically maximum operating range of the smooth‐torque operation for a switched reluctance drive (SRD). The maximum operating range can be determined by the authors previous work, based on which a novel direct instantaneous torque control (DITC) is proposed for four‐phase 8/6 switched ...

Advanced Robotics Research, EarlyView.WorMa is an amphibious undulatory robot that uses Center of Mass redistribution as the sole terrain adaptation mechanism. This mechanism is based on internal fluid mass redistribution through a pump‐driven latex balloon system that creates three profiles: head‐biased, balanced, and tail‐biased.

International Transactions on Electrical Energy SystemsDirect instantaneous torque control (DITC) is a method for torque control in the switched reluctance motor (SRM). In conventional DITC, due to the fixed turn-on and turn-off angles, the presence of negative torque and significant torque ripple is ...

Direct Torque Control of a 4-Phase Switched Reluctance Machine
, 2011 Due to its doubly salient structure and highly nonlinear behavior, the Switched Reluctance Machine (SRM) operates with very high torque ripple. To overcome these inconveniences different average and instantaneous torque control techniques were developed.

Dual‐Mode Gripper With Suction and Shape‐Adaptive Freezing Grasps
Advanced Robotics Research, EarlyView.This study presents a dual‐mode robotic gripper that combines vacuum suction with a shape‐adaptive freezing grasp. The freezing mode uses a compliant rubber membrane, a sprayed water layer, and dry‐ice powder to generate ice‐mediated adhesion while conforming to complex geometries.

Active Speed Compensation Method of Direct Torque Control System and Stability Analysis
Advances in Mechanical Engineering, 2015 By analyzing characteristics of the DTC (direct torque control) system in electrical driving system, a shortcoming of the classical DTC method is to point out that it is unable to decouple the mutual interference between torque and speed, so that when a ...
