Research ArticleOpen accessControl of Incoming H2/O2 Flows in a PEM Fuel CellDhia Mzoughi, Nabila Khili, Hatem Allagui, Abdelkader MamiIt has become crucial, with the dwindling of energy resources related to the depletion risk of fossil and fissile resources, to find energy alternatives which have the same properties as those of a hydrocarbon in terms of transport and storage. In this context, the fuel cell appears as a very serious element both at the industrial and research levels. The … …American Journal of Applied Sciences, Vol. 12, Issue 1 · 26 Feb 2015 · 7,276 accessesView PDF Cite

Research ArticleOpen accessANALYSIS OF MICROSTRIP PATCHES ANTENNAS ARRAY BY USING A NEW BOND GRAPH TECHNOLOGYRiadh Mehouachi, Taghouti Hichem, Abdelkader MamiThis study is the only one that combines the microstrip patch antennas representing the microwave domain and the bond graph technique representing the automatic domain. In this study, we propose a new methodology to analyses the microstrip patch antennas arrays: It is the bond graph technique and the wave scattering formalism. This method helps us to achieve our purpose which … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 30 Jun 2014 · 6,555 accessesView PDF Cite

Research ArticleOpen accessThermal Control of a Greenhouse by Variation in Ventilation Rate using a Fuzzy Parallel Distributed Compensation Controller with an RST Regulator in Each RuleElyes Feki, Amine Chouchaine, Abdelkader MamiProblem statement: The greenhouse has uncontrollable inputs that affect its climate, which arises the difficulty to regulate its inside temperature. The solution can be found using a multi-system approach like the Takagi-Sugeno System from which a design of a Parallel Distributed Compensation (PDC) controller is performed. However, a stability problem arises and was negotiatesd in general based on a Lyapunov … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 27 Apr 2012 · 7,098 accessesView PDF Cite

Research ArticleOpen accessDiscussion around the Scattering Matrix Realization of a Microwave Filter using the Bond Graph Approach and Scattering FormalismHichem Taghouti, Abdelkader MamiProblem statement: Further to research works made previously and which use collectively the scattering formalism and bond graph technique for the modeling of a physical systems often working in high frequencies, we propose, in this article, a comparative study (discussion) for the scattering matrix realization of a high-frequency physical system. Approach: This discussion is based, on the one hand, on … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 7 Feb 2012 · 7,188 accessesView PDF Cite

Research ArticleOpen accessApplication of Adaptive Predictive Control to a Newborn IncubatorMed Aymen Zermani, Elyes Feki, Abdelkader MamiProblem statement: This study presents an application of Indirect Adaptive Generalized Predictive Control (IAGPC) of an incubator for newborn, in order to improve the performance of temperature control. Approach: Analysis of physical phenomena of incubator was involved together knowledge of the dynamic behavior. Incubator was identified by means of Recursive Least Square (RLS) technique associated with a projection of the … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 13 Jul 2011 · 8,242 accessesView PDF Cite

Research ArticleOpen accessModeling Method of a Low-Pass Filter Based on Microstrip T-Lines with Cut-Off Frequency 10 GHz by the Extraction of its Wave-Scattering Parameters from its Causal Bond Graph ModelHichem Taghouti, Abdelkader MamiProblem statement: This study presented a jointly application of bond graph technique and wave-scattering formalism for a new realization called scattering bond graph model which has the main advantage to show up explicitly the different wave propagation. Approach: For that, we proposed to find the scattering matrix from the causal bond graph model of a low-pass filter based on Microstrip … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 4 Nov 2010 · 8,262 accessesView PDF Cite

Research ArticleOpen accessVoltage Oriented Control Applied to a Grid Connected Photovoltaic System with Maximum Power Point Tracking TechniqueRym Marouani, Abdelkader MamiProblem statement: This study presented a grid connected photovoltaic system with voltage oriented control. This system contains the problem of degradation of photovoltaic power with climatic factors and the problem of synchronization of currents to be injected to the grid. Approach: In order to optimize the photovoltaic energy generation, we developed a new maximum power point tracking algorithm and we … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 8,693 accessesView PDF Cite
