Design of NSGA-III Tuned FPC for AMSS

Research Article of American Journal of Computer Sciences and Applications Design of NSGA-III Tuned FPC for AMSS Fengyang Lu1, Xiaolu Xu1, Hengbo Zhao1 1Luoyang Optoelectronic Technology Development Center, Luoyang, China. Airborne missile servo system (AMSS) is a complex time-varying nonlinear system and the design of which is a multi-objective optimization problem. Fuzzy PID controller (FPC) is demonstrated appropriate for complex time-varying nonlinear systems but the design of which needs a tedious trial and error process. Non-dominated Sorting Genetic Algorithm III (NSGA-III) is a multi-objective evolutionary algorithm with good generality and robustness which can do a big favor for parameter tuning of complex system. This paper develops NSGA-III for parameter tuning in design process of FPC. Resulting FPCs are tested with model of AMSS on simulink. For further comparison, performance of conventional PID controller and sectional PID controller which is widely used in the engineering are also shown. Comparison shows that NSGA-III tuned FPCs have the better performance in AMSS. Keywords:  NSGA-III; FPC; AMSS ...

Ascertaining the impact of Temperature, Rainfall, Water level, and Water discharge on Sediment Yield

Research article of American Journal of Computer Sciences and Applications Ascertaining the impact of Temperature, Rainfall, Water level, and Water discharge on Sediment Yield Balogun O*, Ogunseye A.A, Hinmikaiye J, Adegbenle A.A, Oyebode A.A, Akinshola J Department of Computer Science Babcock University, Nigeria The state of our natural environment is continuously changing. Various texts, global environmental monitoring bodies and environmental focused research groups agree that the deterioration, if not checked, will in the nearest future make it impossible for all living things to continue to exist in the ways we are accustomed to. As Earth’s temperature steadily increases, so has its sea level. This has brought about a lot of changes in the landscape of different catchment areas which is as a result of flooding. Flooding, in turn, has also resulted in death and proliferation of water borne diseases This work is motivated by the need to understand what factors mostly affect sediment yield in order to safe guard against its effects. The work takes a look into temperature, rainfall, water level, and water discharge factors from Oyan gauging station of the Ogun-Osun River basin, in the south western part of Nigeria. Our results show that all factors considered have a Sconsiderable effect on sediment yield. Keywords:impact of Temperature, Rainfall, Water level, and Water discharge, Sediment Yield ...

An overview of Artificial neural network

Review article of American Journal of Computer Sciences and Applications An overview of Artificial neural network Emon Md Mohaiminul Islama aChongqing University Of Science And Technology, Shapingba, Chnongqing,China Neural networks represent a brain metaphor for information processing. These models are biologically inspired rather than an exact replica of how the brain actually functions. Neural networks have been shown to be very promising systems in many forecasting applications and business classification applications due to their ability to learn from the data. This article aims to provide a brief overview of artificial neural network.The artificial neural network learns by updating the network architecture and connection weights so that the network can efficiently perform a task. It can learn either from available training patterns or automatically learn from examples or input-output relations. Keywords: review, artificial neural network ...

Phase Modulated OFDMA System, Study and Investigations

Research article of American Journal of Computer Sciences and Applications Phase Modulated OFDMA System, Study and Investigations Farouk A. K. Al-Fuhaidy, Faisal Saif Alkamali, and Khaled Al-sofy Department of electrical engineering, Ibb University, Ibb-Yemen In this paper, a DFT- based OFDMA with phase modulation (DFT-OFDMA-PM) system is proposed. The proposed system exploits the advantages of PM, the constant envelope (CE) signal, and the ability to improve the diversity of multipath channels. The performance of the proposed system in terms of bit error rate (BER) is studied and investigated using simulation. An investigation of the proposed system, the DFT-OFDMA-PM, results is carried and compared to the recently proposed DCT-OFDMA-PM system and the conventional systems without PM. Moreover, the key parameter, the modulation index, which affects the performance of the PM systems, is also studied and the optimum value is chosen via simulation. The simulation results for the proposed system show the effectiveness of the proposed system for broadband communications. Keywords: Phase Modulated OFDMA System, Study, Investigations ...
