Research ArticleOpen accessA Control Strategy for Photovoltaic-Solid Polymer Electrolysis System Based on Surface Temperature of PV PanelRiza Muhida, Wahyudi, Rifki Muhida, Ahmad Unggul PriantoroProcesses to produce hydrogen from solar photovoltaic powered water electrolysis using solid polymer electrolysis are reported. An alternative control of maximum power point tracking method based on analysis of PV panel’s surface Temperature for the PV-SPE system was designed and implemented. From this analysis an optimal voltage of PV can be obtained and was realized as a reference voltage of … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,407 accessesView PDF Cite

Research ArticleOpen accessIntelligent Voice-Based Door Access Control System Using Adaptive-Network-based Fuzzy Inference Systems (ANFIS) for Building SecurityWahyudi, Winda Astuti, Syazilawati MohamedSecure buildings are currently protected from unauthorized access by a variety of devices. Even though there are many kinds of devices to guarantee the system safety such as PIN pads, keys both conventional and electronic, identity cards, cryptographic and dual control procedures, the people voice can also be used. The ability to verify the identity of a speaker by analyzing … …Journal of Computer Science, Vol. 3, Issue 5 · 31 May 2007 · 8,547 accessesView PDF Cite

Research ArticleOpen accessFuzzy Anti-windup Schemes for NCTF Control of Point-to-point (PTP) Positioning SystemsWahyudi, Riza Muhida, Momoh J.E. SalamiThe positioning systems generally need a controller to achieve high accuracy, fast response and robustness. In addition, ease of controller design and simplicity of controller structure are very important for practical application. For satisfying these requirements, NCTF (nominal characteristic trajectory following) controller has been proposed as a practical PTP positioning control. However, the effect of actuator saturation can not be … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 7,119 accessesView PDF Cite

Research ArticleOpen accessDesign and Development of Sensor Based Traffic Light SystemA. Albagul, M. Hrairi, Wahyudi, M. F. HidayathullahThe main object of this study was to design and implement a suitable algorithm and its simulation for an intelligent traffic signal simulator. The system developed is able to sense the presence or absence of vehicles within certain range by setting the appropriate duration for the traffic signals to react accordingly. By employing mathematical functions to calculate the appropriate timing … …American Journal of Applied Sciences, Vol. 3, Issue 3 · 6 Mar 2006 · 8,863 accessesView PDF Cite
