The advantages of photovoltaic power generation, such as its eco-friendliness, low maintenance requirements, and lack of noise, are making it as a significant renewable energy source (RES). This framework presents the modeling and control design of PV grid tied system implemented with integrated single ended primary inductance (SEPIC) Luo converter. The main goal of this work includes investigating solar PV system behaviour and creating an effective grid connected solar power. Solar PV module tracks maximum power, with an aid of chaotic cascaded fuzzy a maximum power point tracking (MPPT) has developed. The DC voltage obtained is fed to 1Φ voltage source inverter (VSI) for conversion of AC voltage. In comparison to typical PWM control, the spectrum performance of the examined voltages is improved by adjusting the nominal duty cycle of main switch of SEPIC-Luo converter. So that PV output impedance is equivalent to DC-DC converter's input resistance. Finally, the obtained AC voltage is supplied to 1Φ grid for further applications. With less THD, an efficiency of 96% is achieved when the implementation of the suggested system is carried out using MATLAB/Simulink.

However, obtaining the composites with homogenous distribution of the SiC particles, low porosity and without clustering of reinforcement particles are still a major problem faced by the research community. These kind of casting defects were overcome by the Additive Manufacturing (AM) technology. In this research, AlSi10Mg parts were manufactured by Laser-Powder Bed Fusion (LPBF) method, one of the AM techniques. The mechanical and morphological characteristics of Additive manufactured (AM) samples were compared with the Stir Casted (SC) samples. Both AM and SC samples were analyzed for the porosity% using the Optical Microscope (OM). From the porosity analysis, it was evident that the AM samples shows 14 % reduction in porosity when compared with the SC samples. Mechanical testing such as tensile test, hardness test, fracture toughness test and double shear stress ...

System modelling involves developing a mathematical model by applying the fundamental physical laws of science and engineering. Simulation studies are then conducted based on the developed model using MatlabR2012a for Simulink. In this papers also study behaviour system in terms of time response (e.g., steady state error, a certain rise-time, and overshoot) and compare FLC adverse PID controller.
