Adaptive Feedforward Control Based on Estimated Electromagnetic Parameters upon a Novel Two-Degrees-of-Freedom Actuator with a Unibody Magnetic Circuit

open access: yesEnergies
This paper focuses on the study of the tracking performance of a novel two-degrees-of-freedom (two-DOF) voice coil motor (VCM). Intelligent control algorithms estimate the motor control model by the relationship between the input and output values, and ...

LCL Filter Design and Implementation for Improving Transient Position Tracking Control Performance of Voice Coil Motor

open access: yesIEEE Access, 2020
Voice coil motor (VCM) is widely used in high precision position servo control for its merits of high linearity and no cogging-torque. There are two conventional driving modes: PWM chopper drive and analog drive.

ROV Teleoperation in the Presence of Cross‐Currents Using Soft Haptics

open access: yesJournal of Field Robotics, Volume 42, Issue 6, Page 2580-2593, September 2025.
ABSTRACT The remote operation of underwater vehicles at depth is complicated by the presence of invisible and unpredictable environmental disturbances such as cross‐currents. Communicating the presence of these disturbances to an operator on the surface is made more difficult by the nature of the disturbances and the lack of visible features to ...
