Sensorless Speed Control of Induction Motors with DTC Based on EKF
Volume 3, Issue 4 , March 2009, Pages 1-10
Abstract
Considering the wide usage of induction motors in various industries and the limitation of applying speed sensors in some cases, sensorless drives have became very important and the challenge to increase the accuracy of estimation continues. This paper presents a novel method for sensorless speed ... Read MoreCoronary Artery Detection in X-Ray Angiogram with Fuzzy C-means Clustering Algorithm
Volume 3, Issue 4 , March 2009, Pages 11-20
Abstract
This paper presents an algorithm for the segmentation of Blood Vessels from x-ray angiography of coronary artery images using Matched filters and Otsu thresholding. Identifying these arteries is a difficult process because of the vessel overlapping, and superimposition with various anatomical structures ... Read MoreControl Power Flow in the Presence of Distributed Generators Using Unified Power Flow Controller
Volume 3, Issue 4 , March 2009, Pages 21-27
Abstract
In this paper the power flow control at power systems in the presence of distributed generation is analyzed. The work proposes use ofUnified power flow controller (UPFC) tocontrol the power flow at the load bus by Main supply in coordination with DG source. This work shows that using UPFC leads ... Read MoreRobust Stability and Robust H2 and H-infinity Output-Feedback Control of a Magnetic Bearing System via LMI Optimization
Volume 3, Issue 4 , March 2009, Pages 28-34
Abstract
This paper offers a design procedure for robust stability, robust H-infinity control and robust H2 control via dynamic output feedback for a class of uncertain linear systems. The uncertainties are of norm bounded type. Then in order to support a high-speed energy storage flywheel, these procedures ... Read MoreDesign and Thermal Analysis of a 300 Watt BLDC motor
Volume 3, Issue 4 , March 2009, Pages 35-43
Abstract
This paper presents the mechanical design and transient thermal analysis of a permanent magnet Brushless DC motor to be replaced with an induction motor and its gearbox for a propulsion application requiring 300 W and 220 RPM. This work presents a suitable method for direct motor drive design. The ... Read MoreMarket Estimation of the Telecom Network's Equipments Based on Cobb-Douglas Demand Forecasting Model
Volume 3, Issue 4 , March 2009, Pages 44-59
Abstract
The goal of this paper is to estimate the capital investment in telecom network's equipments, by using Cobb-Douglas model to predict the number of subscribers for the next years of Iran. By presenting a master plan for "fixed telephony", "mobile telephony", "data", "transmission", and "access" networks, ... Read MoreInvestigation of Temperature Effects in 45nm Silicon-on-Diamond MOSFET Transistor
Volume 3, Issue 4 , March 2009, Pages 60-65
Abstract
In this paper, the self-heating effects (SHE) in 45nm Silicon-on-Insulator (SOI) and Silicon-on-Diamond (SOD) are investigated. As a result of the high thermal conductivity of diamond, SHE is much less pronounced in SOD structures. This makes SOD transistors suitable for high power applications were ...
