Model-Free Speed Control of Single-Phase Flux Switching Motor with an Asymmetrical Rotor

CES Transactions on Electrical Machines and Systems
This paper proposes and implements a model-free open-loop iterative learning control (ILC) strategy to realize the speed control of the single-phase flux switching motor (FSM) with an asymmetrical rotor.

Direct Ink Writing 3D Printing of Recyclable and Thermally Stable Vitrimers

Advanced Materials Technologies, EarlyView.
Vitrimers hold great promise in additive manufacturing as defect‐insensitive, repairable, and recyclable feedstocks. A thin‐film additively manufactured process is developed for a high‐performance vitrimer that is difficult to process traditionally.

Taguchi‐based robust design for minimising torque ripple in 6‐slot/2‐pole modular high‐speed permanent magnet motor with manufacturing tolerances

IET Electric Power Applications
A Taguchi‐based robust design strategy is proposed to minimise the torque ripple of a 6‐slot/2‐pole modular high‐speed permanent magnet motor in mass production, accounting for manufacturing tolerances of split gap (Δg), misalignment (Δm), and offset ...

Pattern Formation in Non‐Equilibrium Architected Materials

Advanced Materials Technologies, EarlyView.
This article demonstrates an artificial mechanical system ‐ a robotic metamaterial ‐ as an accessible and versatile platform within which to explore and prescribe the reaction‐diffusion driven pattern formation hitherto associated with comparatively less accessible and versatile non‐equilibrium biological and chemical systems.

Development of Laterally Graded X‐Ray Multilayer Optics

Advanced Materials Technologies, EarlyView.
This work presents the development of laterally graded X‐ray multilayer optics with both constant and variable lateral gradients. By precisely controlling substrate speed profiles and mask design, these multilayers achieve highly accurate lateral gradients and excellent sagittal thickness uniformity, making them ideal for spectroscopy application at ...

Advanced Design for Weakly Coupled Resonators by Automatic Active Optimization

Advanced Materials Technologies, EarlyView.
An Automatic Active Optimization (AAO) strategy integrates machine learning predictors and genetic algorithms in a closed‐loop workflow. By iteratively expanding its dataset with new discoveries, AAO overcomes the limits of conventional methods. This approach finds superior microstructural designs beyond the initial sample space. We demonstrate this on

The Impact of Catalyst Layer Composition and Structure on Performance and Durability of PEMWE Anodes

Advanced Materials Technologies, EarlyView.
This article explores a new type of anode for water electrolysis that uses less iridium, a rare and expensive metal. By combining stable iridium oxide with platinum and carbon‐based materials, the authors create a catalyst layer that maintains strong performance.

Accurate torque control of position sensorless switched reluctance drives

, 2018
Switched reluctance drives (SRDs) are getting more attractive due to the progress in the field of power electronics in the last decades due to their simple mechanical structure and reliability, as well as their potential for low-cost mass production. Well-known disadvantages of SRDs, such as acoustic noise and torque pulsation, can be handled by means ...
