In this study, a novel field-oriented control (FOC) algorithm was proposed in 60° coordinate system for controlling the speed of permanent magnet synchronous motors. The FOC consists several parts which reference currents and feedback are transformed into representation form system. Current regulators typically used to directly obtain voltage vector. structure established by incorporating space...

<div data-canvas-width="397.2227827050999">This paper proposes a fractional order controller (FOC) for the level control problem of coupled tank system, using desired time domain specifications. The system is used in chemical industries storage and mixing liquids. FOC designed analytically direct synthesis method. In method, Bode's ideal loop transfer function chosen as function. has adva...

Las fracturas osteocondrales (FOC) traumáticas de rodilla en la edad pediátrica, son lesiones que acompañan hasta un 30% las luxaciones agudas rótula (LAR). Si no se mantiene una elevada sospecha clínica, es frecuente su retraso diagnóstico, pudiendo generar potenciales complicaciones. A propósito, presentamos el caso paciente 12 años con FOC post LAR pasó inadvertida primera consulta,...

Bananas and plantains (Musa spp.) are among the main staple of millions people in world. Among Musaceae diseases that may limit its productivity, Fusarium wilt (FW), caused by oxysporum f. sp. cubense (Foc), has been threatening banana industry for many years, with devastating effects on economy tropical countries, becoming leading cause changes land use severely affected areas. In this article...

Situational crime deterrence measures like CCTV are not always associated with reductions in fear of crime. This study explores this unexpected finding by investigating the interaction between target type and the presence of a CCTV camera, in order to test the effect this has on impressions of the target and corresponding fear of the location the target was shown in. Participants (n=120) were s...

There is now ample evidence that most perhaps all galactic spheroids host a supermassive BH at their center. This has been assessed using a variety of observational techniques, from stellar and/or gas dynamics to megamasers. Yet another promising technique is offered by the case of the Virgo elliptical NGC 4552, in which early HST/FOC observations revealed a central low-luminosity flare. Subseq...

This paper deals with realization and implementation of a new type fractional order controllers (FOC) based on programmable logic controllers series BR 2005 and their utilization to temperature control with big time constant. As the object was used electrical heater, where controlled value is the temperature of hot air, which is fluctuant from heater.
