It is often accepted as common knowledge that military personnel benefit from decompression time between a war zone and the home station. To capitalize on the potential benefits of a decompression period paired with support services, the U.S. Air Force established the Deployment Transition Center (DTC) at Ramstein Air Base in Germany in July 2010. The DTC provides airmen returning from combat m...

By using the direct torque control (DTC), robust response in ac drives can be produced. Ripples of currents, and flux are oberved steady state. space vector modulation (SVM) applied DTC used for a sensorless induction motor (IM) with fuzzy sliding mode speed controller (FSMSC) is studied this paper. This minimize torque, flux, current pulsations To estimate rotor stator model reference adaptive...

background: x-ray repair cross-complementing group 1 (xrcc1) gene is a dna repair gene and its non-synonymous single nucleotide polymorphisms (snp) may influence dna repair capacity which has been considered as a modifying risk factor for cancer development. methods: a case-control study was conducted to investigate impact of three frequently studied polymorphisms (arg194trp, arg280his and arg3...

Energy storage is a vital aspect for the successful implementation of renewable energy resources on global scale. Herein, we investigated redox cycle nickel dithiocarbamates potential use as catholytes in non-aqueous flow batteries. The unique (Ni(dtc)2) offers ability to better understand these reactions by displaying 2e- chemistry upon oxidation from Ni(II) → Ni(IV) but 1e- reduction Ni(III) ...

This paper presents a Direct Torque Control (DTC) strategy for the five-phase induction motor driven by a three-level five-phase inverter in order to improve the performance of the five-phase induction motor. In the proposed DTC technique, only 22 voltage vectors out of 243 available voltage vectors in a three-level five-phase inverter are selected and are divided in 10 sectors each with a widt...

The direct torque control (DTC) speed control scheme of an induction motor surpasses the vector control in the sense that it controls the torque directly and does not use transformations and current modulator. In the traditional direct torque control (DTC) of induction motor, the low order harmonic component of stator current is very large when the motor is running at low speed. It leads to hig...

In conventional direct torque control (DTC) of induction machines, undesirable flux and torque ripples are produced. These occur since non of the selected inverter's voltage vectors are able to generate the exact voltage required to produce the desired changes in the electromagnetic torque and stator flux linkage in most of the switching instances. In addition, when direct torque control is imp...

امروزه به خاطر پیشرفت در عناصر نیمه هادی قدرت و به طبع پیشرفت در روش های کنترل درایوهای سرعت متغیر، ماشین های القایی (im) جایگزین ماشین های جریان مستقیم (dc) در صنعت شده اند. در دهه اخیر روش کنترل مستقیم گشتاور (dtc) بر خلاف روش های کنترل برداری، به خاطر سادگی ساختار، پیاد ه سازی آسان، همراه با پاسخ دینامیکی سریع مورد توجه فراوان قرار گرفته است. dtc، روش کنترلی است که موتور و مبدل را به صورت یک...
