Research ArticleOpen accessEvery word in the titleANALISIS OF THE NONLINEAR DISTRIBUTED CONTROL SYSTEM'S SUSTAINABILITYAlexander B. Chernyshev, Karina V. Martirosyan, Alexander V. MartirosyanSystems' stability is the topical issue of control systems' development province. In this study the research of methodology of the nonlinear distributed control systems' stability assessment is conducted. Research of the standard distributed links' frequency surfaces is executed, limit characteristics of the parameters influencing by sight of spatial hodograph are investigated. The purpose of the work is to present the … …Journal of Mathematics and Statistics, Vol. 10, Issue 3 · 11 Jul 2014 · 6,712 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA NOVEL ARTIFICIAL HYDROCARBON NETWORKS BASED SPACE VECTOR PULSE WIDTH MODULATION CONTROLLER FOR INDUCTION MOTORSHiram Ponce, Luis Ibarra, Pedro Ponce, Arturo MolinaMost of machine-operated industrial processes implement electric machinery as their work sources, implying the necessary improvement of control techniques and power electronics drivers. Many years have passed since the control conflicts related to induction motors have been overcome through torque-flux control techniques so their advantages over direct current motors have made them to be the most common electric actuator found … …American Journal of Applied Sciences, Vol. 11, Issue 5 · 26 Feb 2014 · 7,046 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEmbedded Computer Based Active Vibration Control System for Vibration Reduction of Flexible StructuresVenkata Ratnam Tatavolu, Seetha Ramaiah PanchumarthyResearch on Active Vibration Control System (AVCS) is being carried out to reduce structural vibrations caused by unwanted vibrations in many application areas such as in space, aircraft structures, satellites, automobiles and civil structures (bridges), particularly at low frequencies. The unwanted vibration may cause damage to the structure or degradation to the structure’s performance. The AVCS comprises physical plant, a … …Journal of Computer Science, Vol. 9, Issue 7 · 15 Jun 2013 · 6,555 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Model for Congestion Control of Transmission Control Protocol in Mobile Wireless Ad Hoc NetworksAdib M. Monzer Habbal, Suhaidi HassanTransmission Control Protocol (TCP) is a fundamental protocol in the TCP/IP Protocol Suite.TCP was well designed and optimized to work over wired networks where most packet loss occurs due to network congestion. In theory, TCP should not care whether it is running over wired networks, WLANs, or Mobile Ad hoc Networks (MANETs). In practice, it does matter because most TCP … …Journal of Computer Science, Vol. 9, Issue 3 · 24 Apr 2013 · 7,381 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRobust Positioning of Laser Beams Using Proportional Integral Derivative and Based Observer-Feedback ControlKwabena A. Konadu, Sun Yi, Wonchang Choi, Taher Abu-LebdehHigh-precision positioning of laser beams has been a great challenge in industry due to inevitable existence of noise and disturbance. The work presented in this study addresses this problem by employing two different control strategies: Proportional Integral Derivative (PID) control and state feedback control with an observer. The control strategies are intended to stabilize the position of a laser beam … …American Journal of Applied Sciences, Vol. 10, Issue 4 · 19 Apr 2013 · 6,874 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleApplication of Optimal Control to the Epidemiology of Fowl Pox Transmission Dynamics in PoultryUdofia Ekere Sunday, Inyama Simeon ChiomaProblem statement: In this study, we present the mathematical model of the transmission dynamics of fowl pox infection in poultry. Approach: It describes the interaction between the susceptible and the infected birds which results in a system of ordinary differential equation. Introducing the control which represents the effort in applying chemoprophylaxis control u1 and treatment control u2 in birds with … …Journal of Mathematics and Statistics, Vol. 8, Issue 2 · 13 Jun 2012 · 6,957 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Optimal Rate Adjustment Algorithm for Medium Access Control Protocol in 802.11 Multi Hop Ad Hoc NetworksT. Ravichandran, K. SaravananProblem statement: Medium Access Control (MAC) protocol plays an important role in providing a fair and efficient allocation of limited bandwidth in wireless LANs. In IEEE 802.11 standard protocol, data rate selection is not specified. Rate control is the process of switching data rates dynamically based on channel conditions, with the target of selecting the rate that will provide the … …Journal of Computer Science, Vol. 8, Issue 7 · 9 Jun 2012 · 7,030 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSynthesis 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 · 7,273 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePurpose-based Versus Flow-Based Access Control for PrivacySabah Al-Fedaghi, Bashayer Al-Babtain, Maha Al-FahadProblem statement: Data protection legislation requires handling of Personal Identifiable Information (PII) in special ways to guarantee privacy. Specifically, the notion of handling purpose plays an important role in current access control mechanisms that allow only actions corresponding to intended purposes. A problem that arises in this context is how to ensure that PII is used solely for the intended … …Journal of Computer Science, Vol. 8, Issue 4 · 8 Feb 2012 · 6,821 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDerivation of the Limits for Control Chart Using the Median Absolute Deviation for Monitoring Non-Normal ProcessK. S. Adekeye, P. I. AzubuikeProblem statement: The Shewhart and S control charts, in the literature, were combined to evaluate the stability of a process. These charts were based on the fundamental assumption of normality of the quality characteristics under investigation. Approach: In practice, the normality assumption was often violated by real life data, therefore, use of the Shewhart and S control charts on real … …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 24 Dec 2011 · 8,440 accessesView PDFCite
