Research ArticleOpen accessIn the keywordsMobile Node Speed Detection Mechanism in Hierarchical Mobile Internet Protocol (IPv6)Zulkeflee Kusin, Mohamad Shanudin ZakariaProblem statement: IETF has introduced Hierarchical Mobile IPv6 (HMIPv6) to support mobility problem in the next generation Internet Protocol (IPv6). The key concept behind this protocol is the usage of Mobility Anchor Point (MAP) located at any level router of network to support hierarchical mobility management and seamless handover. The distance MAP selection in HMIPv6 causes MAP overloaded as the … …Journal of Computer Science, Vol. 7, Issue 9 · 27 Jul 2011 · 6,614 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAdaptive Controllers for Permanent Magnet Brushless DC Motor Drive System using Adaptive-Network-based Fuzzy Interference SystemV.M. Varatharaju, Badrilal Mathur, UdhayakumarProblem statement: The tuning methodology for the parameters of adaptive speed controller causes a transient deviation of the response from the set reference following variation in load torque in a permanent-magnet brushless DC (BLDC) motor drive system. Approach: This study develops a mathematical model of the BLDC drive system, firstly. Secondly, discusses a design of the closed loop drive system … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 19 Jul 2011 · 6,941 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImproving Reliability and Productivity of an Aluminum Extruder by Implementation of Direct Torque Control TechnologyMazouz A. SalahatProblem statement: The linear motor drive is widely used in driving an extrusion puller in an aluminum extrusion industry. The main disadvantage of this drive is manual and step-wise torque control. This research was done to replace the linear motor drive by AC drive with direct torque control technology. Approach: Mathematical calculations were carried to select an AC drive which … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,267 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTransducer for Tension Force Measuring of Strip MaterialsEmad Said AddasiIn winding-up motor drive systems, such as that used in textile industry, it is very important to get a constant tension force for the winding strip material (thread) and to reduce its oscillations. This study recommends a transducer with a special design to be used in the mentioned motor drive systems. By using a piston damper, spring, levers, slider and … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,967 accessesView PDFCite
Research ArticleOpen accessIn the keywordsReal Time Hybrid Controller Implementation for Switched Reluctance Motor DriveS. Paramasivam, R. ArumugamThis study presents the real time hybrid controller implementation for a Switched Reluctance motor Drive. The developed hybrid control law consists of Proportional Integral (PI) controller at steady state, PI-type fuzzy logic controller (FLC) at transient state and a simple logic controller between steady and transient states to achieve desired performance at various operating conditions under soft chopping operation. The … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 7,240 accessesView PDFCite
Research ArticleOpen accessIn the keywordsField Evaluation of a Pneumatic Prototype Machine Designed to Control the Colorado Potato Beetle in Potato CropsSaad Almady, Mohamed KhelifiThe Colorado Potato Beetle (CPB), Leptinotarsa decemlineata Say, 1824, is a major insect pest of potato plants. It can greatly reduce potato yields if left uncontrolled. The most effective method of controlling the CPB is to apply chemical insecticides during its life cycle. However, the CPB tends to develop resistance to chemicals. Therefore, its control is difficult. This has prompted … …American Journal of Agricultural and Biological Sciences, Vol. 17, Issue 1 · 26 Dec 2022 · 6,403 accessesView PDFCite

Research ArticleOpen accessIn the keywordsHarmonics Phase Shifter for a Three-Phase System with Voltage Control by Integral-Cycle Triggering Mode of ThyristorsI. Badran, A.L. Mahmood, M.T. LazimIn integral-cycle triggering mode of voltage control, subharmonic as well as higher order harmonic components are generated in the load voltage waveforms of a three-phase system. These harmonic components are found to be unbalanced in phase displacement. The correction of the unbalanced phase displacement angles of a particular subharmonic or higher order harmonic for this type of triggering is investigated … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,110 accessesView PDFCite
