Research ArticleOpen accessIn the keywordsExtending UML-RT for Control System ModelingQimin Gao, L. J. Brown, L. F. CapretzThere is a growing interest in adopting object technologies for the development of real-time control systems. Several commercial tools, currently available, provide object-oriented modeling and design support for real-time control systems. While these products provide many useful facilities, such as visualization tools and automatic code generation, they are all weak in addressing the central characteristic of real-time control systems design, … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 6,746 accessesView PDFCite
Research ArticleOpen accessIn the keywordsKinematics and Forces to a New Model Forging ManipulatorRaffaella Aversa, Relly Victoria V. Petrescu, Bilal Akash et al.Forging manipulators have become more prevalent in the industry of today. They are used to manipulate objects to be forged. The most common forging manipulators move on a railway to have a better precision and stability. Heavy payload forging manipulators systems are normally characterized by a large load output and a large capacitive load input as well. The relationship between … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 3 Jan 2017 · 8,173 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMulti-Controlled Wheelchair for Upper Extremities DisabilityChadi F. RimanPeople with motor disabilities are trying to be more autonomous by using an electric wheelchair with a conventional joystick control. However, a problem arises when these people are suffering from upper extremities disability such as tetraplegia. Several methods were implemented such as voice control, chin control, eye-blink, sip-and-puff, but each has its advantages and disadvantages. Furthermore, in some situations a … …Journal of Mechatronics and Robotics, Vol. 2, Issue 1 · 3 Dec 2018 · 7,247 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Drives and Control Integrated Time-Domain Dynamic Analysis and Modeling Approach Applied To Ultra-Precision Machine ToolsTianjian Li, Shijin Chen, Haijun Zhang, Kai ChengProblem statement: Machines dynamic performance depends not only upon the mechanical structure and components but also the drives and control system. However, the design of the machines is still at the nascent stage by working on an individual machine basis, hence lacks generic scientific approach and design guideline. Approach: Using computer models integrated drives and control system to predict the … …Current Research in Nanotechnology, Vol. 2, Issue 1 · 29 Jul 2011 · 8,094 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFault Tolerant Control Using Proportional-Integral-Derivative Controller Tuned by Genetic AlgorithmS. Kanthalakshmi, V. ManikandanProblem statement: The growing demand for reliability, maintainability and survivability in industrial processes has drawn significant research in fault detection and fault tolerant control domain. A fault is usually defined as an unexpected change in a system, such as component malfunction and variations in operating condition, which tends to degrade the overall system performance. The purpose of fault detection is … …Journal of Computer Science, Vol. 7, Issue 8 · 15 Jul 2011 · 6,482 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEvaluation of Soil Moisture Sensors under Intelligent Irrigation Systems for Economical Crops in Arid RegionsMohamed Said Abdall El Marazky, Fawzi Said Mohammad, Hussein Mohamed Al-GhobariProblem Statement: In irrigation water management, irrigation water use represents a substantial opportunity for agriculture water savings. Automation of irrigation systems, based on Soil Moisture Sensors Systems (SMSS) has the potential to provide maximum water use efficiency by maintaining soil moisture at optimum levels. Approach: The objective of this research was to evaluate the performance of soil moisture sensors under … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 24 Jun 2011 · 8,907 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRehabilitation of a Human Arm Supported by a Robotic Manipulator: A Position/Force Cooperative ControlHaifa Mehdi, Olfa BoubakerProblem statement: The assistance of person with limited ability of arm movement is necessary for rehabilitation reasons. This aid is required not only to cover the human performances of the arm in motion and force but also to have a strictly stable dynamics. In this study, we proposed a cooperative system between a disabled arm and a robotic manipulator to … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,459 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA New Engineering Method for Fuzzy Reliability Analysis of Surge Control in Centrifugal CompressorAhmed Hafaifa, Ferhat Laaouad, Moulod GuemanaProblem statement: The surge phenomenon in the centrifugal compressor, the non-linearities and uncertainties of the compression system make it impossible to use a conventional controller over a wide range of operation. Approach: A new dual fuzzy controller for nonlinear model of compression system was proposed in this study. This fuzzy controller was designed that consisted of active surge control and … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 8,229 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPreliminary Experimental and Finite-Element Numerical Assessment of the Structural Performance of SMA-Reinforced GFRP SystemsFilipe Amarante dos Santos, Chiara BedonIn this study, the feasibility and potentiality of a novel design concept is explored by means of small scale experimental tests and Finite-Element numerical simulation. Taking advantage of the intrinsic potentiality of Shape-Memory Alloys wires able to work as adaptive actuators when subjected to joule heating, a 'smart-GFRP' concept consisting in Glass-Fiber-Reinforced-Polymer (GFRP) structural members with a SMA reinforcement is … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 27 Sep 2016 · 8,298 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCASE STUDY OF THE OPTIMIZING THE AUTOMOTIVE MANUFACTURING SYSTEMS EFFICIENCY VIA APPLYING NEW METHOD OF SCHEDULINGSeyedehfarzaneh Nojabaei, Matthew FranchettiEfficiency is becoming a pivotal aspect in each manufacturing system and scheduling plays a crucial role in sustaining it. The applicability of distributed computing to coordinate and execute jobs has been investigated in the past literature. Moreover, it is significant that even for sensitive industrial systems the only criterion of allocating jobs to appropriate machines is the FIFO policy.
