Research ArticleOpen accessIn the abstractVoltage Stability of Short Transmission Line Equipped with a Thyristor Controlled Series CapacitorPrechanon KumkratugIt is becoming increasingly important to fully utilize the existing transmission system assets due to environmental legislation, rights-of-way issues, costs of construction and deregulation policies that introduced in recent years. The Thyristor Controlled Series Capacitor (TCSC) has been proposed for the better control power flow and dynamic performance. The exact short transmission line model consists of the resistance and reactance. … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 8 Nov 2012 · 6,696 accessesView PDFCite
Research ArticleOpen accessIn the abstractA 2-12 GHz Low Noise Amplifier Design for Ultra Wide Band ApplicationsV. Vaithianathan, J. Raja, R. SrinivasanProblem statement: The Low Noise Amplifier (LNA) is a core block of an Ultra Wide Band (UWB) receiver since it amplifies a very weak signal received at the antenna to acceptable levels while introducing less self-generated noise and distortions. The LNA design poses a unique challenge as it requires simultaneous optimization of various performance parameters like power gain, input matching, … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 9 Jun 2012 · 7,397 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis of Robust Dynamic Controller, Model Predictive Control BasedMohamed Adel Sellami, Elyes Maherzi, Mongi BesbesProblem statement: More advanced control techniques have been developed in recent decades following the great progress of calculations means. Without considering the constraints on system variables, the response of controlled system moves away from the desired response. Hence the control strategy must provide the ability to integrate these constraints in the design phase of the controller. Approach: This study presents … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 16 Mar 2012 · 7,267 accessesView PDFCite
