Optimal digital control of a three-phase four-leg voltage source inverter

TURKISH JOURNAL OF ELECTRICAL ENGINEERING & COMPUTER SCIENCES, 2016
This paper presents a three-dimensiona (3-D) space vector pulse width modulation (SVPWM) technique via a 4 4 orthonormal transformation matrix that has been used as a new approach in controlling a three-phase four-leg voltage source inverter (VSI). A fully optimal digital control scheme for the closed-loop regulation of the three-phase four-leg VSI ...

Design and Characterization of a Two‐Dimensional Soft Array Based on Cooperative Dielectric Elastomer Actuators

Advanced Functional Materials, EarlyView.
A fully polymeric two‐dimensional array of Dielectric Elastomers enables self‐sensing, cooperative actuation, and large‐stroke operation in a DE‐based autonomous conveyor. Based only on voltage and current measurements at actuator level, the system detects the presence of a ball and subsequently drives it toward a target position.

Programming of Complex Magnetic Profiles Enforced by 4D Printed Magnetic LCE Actuators

Advanced Materials, EarlyView.
A 4D printing‐enabled magnetic programming strategy is introduced in which thermally actuated liquid crystal elastomers are magnetized in their target shape to encode complex three‐dimensional magnetic profiles. The resulting actuators achieve multistate shape morphing and programmable locomotion under low magnetic fields, without requiring specialized
