PID-fuzzy of DC motors using Raspberry PI
Visión Electrónica, 2020 This article describes the implementation of a fuzzy and a PID control system for the velocity and torque of a DC power motor, based in the variation of the armor current and its duty cycle. The control system has been applied to a medium power DC motor,

Influence of the amount of permanent-magnet material in fractional-slot permanent-magnet synchronous machines [PDF]
, 2014 The efficiency of permanent-magnet (PM) synchronous machines with outer rotor and concentrated windings is investigated as a function of the mass of magnets used, keeping the power, volume, and mechanical air-gap thickness constant. In order to be useful

Electronics Letters, 1999 A new discrete sampling based pulsewidth modulation (PWM) strategy is presented which closely reproduces the characteristics of analogue hysteresis band modulation. This sampling based strategy does not require the solution of nonlinear transcendental equations, which are characteristic of the analogue method and therefore limit its application.

The rs10191329 Risk Allele Is Associated With Pronounced Retinal Layer Atrophy in Multiple Sclerosis
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective To investigate whether the rs10191329 risk allele in the DYSF–ZNF638 locus, which is implicated in central nervous system resilience rather than immune‐mediated pathology, is associated with retinal layer thinning, a biomarker of neuroaxonal damage in relapsing multiple sclerosis (RMS). Methods From a prospective observational study,
