Magnetic Continuum Device with Variable Stiffness for Minimally Invasive Surgery

Advanced Intelligent Systems, Volume 2, Issue 6, June 2020., 2020
Herein, a variable stiffness continuum device controlled by external magnetic fields is presented for medical applications. The device is composed of several sections whose stiffness is controlled to be either stiff or soft. The magnetic torque is used to remotely control the shape of the soft sections, whereas the stiff sections remain unchanged, thus

Design and laboratory test of black‐start control mode for wind turbines

Wind Energy, Volume 23, Issue 3, Page 763-778, March 2020., 2020
Abstract In this article, an operational strategy and control concept for wind turbines (WTs) are described, which would allow them to actively contribute to black‐start events after major power system outages. The approach is based on (a) a new generator/converter control strategy implementing a so called virtual synchronous machine (VSM) and (b) a ...

Modeling of Tension Control System with Passive Dancer Roll for Automated Fiber Placement

Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
The fiber tension should be kept constant during the automated placement of fiber prepreg. The velocity of the fiber placement end‐effector moving on complex aircraft panel mould surface varies rapidly, which greatly disturbs the precision of tension control.
