Fractional order Adaptive Terminal Sliding Mode Controller Design for MPPT in a Solar Cell under Normal and Partial Shading Condition
In this paper, by combining fractional calculus and sliding mode control theory, a new fractional order adaptive terminal sliding mode controller is proposed for the maximum power point tracking in a solar cell. To find the maximum power point, the incremental conductance method has been used. First, a fractional order terminal sliding mode controller is designed in which the control law depend...
متن کاملThe Effect of Solar Radiation Data Types on Calculation of Tilted and Suntracking Solar Radiation
Energy yield assessment of photovoltaic systems is inherently non-linear. The calculation chain starts with simulation of solar radiation, where many factors are considered: sun’s position, terrain, properties of the atmosphere and cloudiness to determine the absolute value of global irradiance and the ratio of diffuse and direct components. The ratio of direct and diffuse components influences...
متن کاملActive Solar Shading
Solar shading can be used to decrease the cooling power demand and cooling energy use but that also reduces the possible benefit for heating with the incoming solar radiation when there is a heating need. The apparent solution is to shade when there is a cooling need and allow solar gains when there is a heating need. This paper presents energy use simulations on such a system set up in a theor...
متن کاملConcurrent engineering approach to plastic optics design
Engineering can be seen as a balancing act in which several partially of fully conflicting needs have to be satisfied with one single solution. Concurrent engineering (CE) is a philosophy that aims for better products by improving the different design processes inside the whole development process. This is achieved by emphasizing holistic thinking. In this thesis the most relevant terms and def...
متن کاملCharacterization and Photo-catalytic Efficiency of MnFe2O4/Zn2SiO4 for Aniline Degradation Using Box-Behnken Experimental Design and Simulated Solar Radiation
In this research, Zn2SiO4 as a support and MnFe2O4 as a main photo-catalyst were individually syn-thesized and MnFe2O4 was fixed on Zn2SiO4 with solid state dispersion method. MnFe2O4 nano pho-to-catalyst was synthesized by co-precipitation method and reflux condition for 12 hours at 85°C in the presence of urea. For identification of catalysts Fourier-transform infrared (FTIR) sp...
