Current Tracking Adaptive Control of Brushless DC Motors

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
In this paper, the current tracking for Brushless Direct Current motors is approached considering uncertainty in the parameters of the motor's model. An adaptive control scheme to compensate electrical parameters uncertainty is proposed without requiring any knowledge of the mechanical parameters.

Dipoles, unintentional antennas and EMC [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2008
Radiated emissions from equipment commonly originate from electronic circuits that act as electric dipoles created by the signal voltage between the signal conductors or as magnetic dipoles formed by the signal current flowing in a loop.

An Adaptive Human Pilot Model With Reaction Time Delay for Enhanced Adaptive Control in Piloted Systems

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
This work introduces an adaptive human pilot model that captures pilot time‐delay effects in adaptive control systems. The model enables the prediction of pilot–controller interactions, facilitating safer integration and improved design of adaptive controllers for piloted applications.

Slim dual‐polarised antenna with omnidirectional patterns for WLAN applications

open access: yesElectronics Letters, 2019
A slim dual‐polarised antenna with omnidirectional patterns is proposed for wireless local area network (WLAN) applications. The antenna is a composition of a modified J‐type antenna for vertical polarisation and two crossed‐loop antennas for horizontal ...

Antenna showers with one-loop matrix elements [PDF]

open access: yesJournal of High Energy Physics, 2013
AbstractWe consider the probability for a colour-singlet$ q\overline{q} $pair to emit a gluon, in strongly and smoothly ordered antenna showers. We expand to second order inαsand compare to the second-order QCD matrix elements forZ→ 3 jets, neglecting terms suppressed by$ {1 \left/ {{N_C^2}} \right.} $.

A Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
Block Diagram of the Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller. ABSTRACT This article introduces a discrete‐time robust adaptive one‐sample‐ahead preview super‐twisting sliding mode controller. A stability analysis of the controller by Lyapunov criteria is developed to demonstrate its robustness in handling both ...

Spectrum and Energy Efficiencies for Multiuser Pairs Massive MIMO Systems With Full-Duplex Amplify-and-Forward Relay

open access: yesIEEE Access, 2015
To achieve insights about the impact of amplified loop interference, we consider a dual-hop fullduplex (FD) massive multiple-input multiple-output (MIMO) amplify-and-forward (AF) relaying system in terms of achievable ergodic rates for each user pair as ...

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

open access: yesAdvanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting
