Modeling and Analysis of Medium Frequency Transformers for Power Converters

A mathematical model of a 3-phase medium frequency transformer (MFT) in an isolated DC-DC power converter, suitable for electromagnetic transient and steady-state simulation is developed. The transformer modeling methods are reviewed, and the Lagrange energy method is used to derive a physically motivated model for circuit analysis.

Motion Planning and Experimental Validation for an Autonomous Bicycle

This paper introduces a prototype autonomous two-wheeled vehicle developed for experimental verification of motion planning and control algorithms. Finally, it presents and discusses experiments run on the actual vehicle for a particular maneuver. It emphasizes the differences between the trajectories created by different vehicle models.

A Lightweight Force-Controllable Wearable Arm Based on Magnetorheological-Hydrostatic Actuators

This paper studies the feasibility of using magnetorheological (MR) clutches coupled to a low-friction hydrostatic transmission.  This combination provides a highly effective yet lightweight, force-controllable supernumerary robotic arm (SRL). Experimental studies conducted on a one-DOF test bench and validated analytically demonstrate a high force bandwidth (>25 Hz) and an excellent ability to control interaction forces even when interacting with an external impedance.

Active Magnetic Bearing for Ultra-Precision Flexible Electronics Production System

Roll-to-roll printing of flexible electronics on continuous plastic films could enable the production of flexible electronics at high speed and low cost. However, rolling element bearings cannot be deployed because of the precision requirements. Instead, active magnetic bearings (AMB) with optical positioning encoder feedback are used.
