Research ArticleOpen accessEvery word in the titleDrawing Meshed One-Line Diagrams of Electric Power Systems using a Modified Controlled Spring Embedder Algorithm Enhanced with Geospatial DataAlexandre de Assis Mota, Lia Toledo Moreira MotaProblem statement: One-line diagrams are widely used in electrical power systems to provide a graphical view of state of the system and to assess its performance. Several methodologies and algorithms have been proposed to automatically draw the power system’s one-line diagram and provide satisfactory results for radial or small-size meshed networks. Nevertheless, actual power systems models are generally associated to … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 8,096 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleElectric Voltage Control as an Implementation of Neural Network ApplicationsA. A. Al-Rababah, U. A.Al-RababahPresent study was proposed the monitoring of mathematical model of electric voltage source with using neural network for application in control systems as sensor and command signal. The monitoring system, consist of toroidal choke or transformer with high saturated ferromagnetic cores. The input information we receive from current periodic curves. The current was distributed into Fourier or walsh series. The … …Journal of Computer Science, Vol. 4, Issue 10 · 31 Oct 2008 · 6,294 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRobust Electronic Differential Controller for an Electric VehicleA. Ravi, Sankaran PalaniThis study presents an efficient and robust control scheme of electronic differential system for an electric vehicle. The proposed system consists of two Brushless DC motors (BLDC) that ensure the drive of the two back driving wheels of an electric vehicle. Electronic Differential Controller (EDC) ensures the maximum torque and it can control both the driving wheel independently to turn … …American Journal of Applied Sciences, Vol. 10, Issue 11 · 10 Sep 2013 · 7,793 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSpeed Estimation of Adaptive Fuzzy-Controlled Piezo-Electric Motor using MLP-Neural NetworkShebel ALSABBAH, Tariq MUGHRABIThe speed of ultrasonic motor of piezo-electric type is usually measured using mechanical sensors such as pulse encoders. However, these sensors are costly and bulky. In this paper, a numerical speed estimation approach of a piezo-electric motor (PEM) is implemented using multilayer perception neural network (MLP-NN). The proposed model evaluates rotational speed and load torque based on the amplitude and … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 6,785 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDesign of Robust UPFC Controller Using H∞ Control Theory in Electric Power SystemSeyed Abbas Taher, Shahabeddin Akbari, Ali Abdolalipour, Reza HemattiAn industrial plant, such a power system, always contains parametric uncertainties. In the design of a controller the uncertainties have to be considered. Otherwise, if the real plant differs from the assumed plant model, a controller, designed based on classical controller design approaches, may not ensure the stability of the overall system. In this paper design of robust control for … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 7,090 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComparison of Different Control Strategies in GA-Based Optimized UPFC Controller in Electric Power SystemsSeyed Abbas Taher, Reza Hematti, Majid NematiThis study presents a study of the application of a Unified Power Flow Controller (UPFC) to control power transmission, generator terminals voltage and better damping of Low Frequency Oscillation (LFO) in Single-Machine Infinite-Bus (SMIB) power system. The UPFC integrates properties of both shunt and series compensations and can effectively alter power system parameters in a way that increases power transfer … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,599 accessesView PDFCite
Research ArticleOpen accessIn the keywordsObject Oriented Modeling of Thermostatically Controlled Devices for Cold Load Pick-upAlexandre de Assis Mota, Lia Toledo Moreira Mota, Claudia Cotrim PezzutoProblem statement: During service restoration, the power level at buses can significantly differ from the one presented under steady-state conditions, demanding an amount of electric power significantly higher than the normal load. Hence, their post-outage behavior must be adequately forecasted in order to permit the development of reliable restoration plans, or to avoid inadequate actions that may lead to a … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 6,847 accessesView PDFCite

Research ArticleOpen accessIn the keywordsCodesign Methodology of Real-time Embedded Controllers for Electromechanical SystemsSlim Ben Saoud, Andreas Gerstlauer, Daniel D. GajskiUnder increasing time-to-market pressures in the electric drives industries, the development time of new algorithms and new control systems including their debugging time must be minimized. This requirement can be satisfied only by using a well-defined system-level design methodology and by reducing the migration time between the algorithm development language and the hardware specification language. In this study, we propose … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,444 accessesView PDFCite
