Putri, Suci Imani (2014) Optimasi Panel Surya Berpenjejak (Sun Tracking System) Dengan Metode Fuzzy Takagi-Sugeno. Magister thesis, Universitas Brawijaya.
Abstract
Secara global penggunaan sel surya meningkat sebagai akibat peningkatan pemanfaatan sumber energi matahari untuk memenuhi kebutuhan energi listrik dunia. Untuk mengoptimalkan penyerapan energi matahari digunakan panel surya berpenjejak (sun-tracking solar system), yang merupakan suatu sistem untuk mengendalikan posisi panel surya agar selalu mengikuti arah dan posisi matahari sehingga sel surya dapat diserap secara maksimal. Pada penelitian ini didiskusikan dan dijelaskan hasil penelitian mengenai implementasi logika fuzzy pada panel surya berpenjejak yang menggunakan motor DC untuk mengatur posisi panel surya. Fuzzifikasi dilakukan menggunakan metode Takagi-Sugeno. Algoritma pengendalian diimplementasikan pada mikrokontroler ATMega 128 menggunakan program BASCOM-AVR. Hasil penelitian menunjukkan adanya peningkatan tegangan keluaran sensor sel surya (Vout) sebesar 0,40V dibandingkan dengan panel surya tanpa perhitungan logika fuzzy. Validasi hasil perhitungan logika fuzzy dengan metode Takagi-Sugeno dengan cara membandingkannya dengan metode Tsukamoto menunjukkan perbedaan hasil pengujian tegangan keluaran sensor sel surya yang tidak signifikan (0,001V), namun komputasi Takagi-Sugeno lebih efisien karena memanfaatkan penggabungan perhitungan logika fuzzy dengan dua keluaran sekaligus, dibandingkan dengan metode Tsukamoto yang melakukan perhitungan pada keluaran fuzzy satu per satu.
English Abstract
Globally, the use of solar cells increased as a result of the increasing utilization of solar energy to meet the needs of the world’s electrical energy. To optimize the absorption of solar energy, tracking solar panels (sun-tracking solar system) is being used, which is a system to control the position of the solar panels to always follow the direction and position of the sun so that the solar cell can be optimally absorbed. In this article, the results of research on the implementation of fuzzy logic in tracking solar panels which uses a DC motor to position the solar panels is being presented. The fuzzification conducted using Takagi-Sugeno method. The control algorithm is implemented in a microcontroller ATMega 128 using BASCOM-AVR program. The results showed an 0.40 Volt increase in the output voltage of the solar cell sensor (Vout) compared to solar panels without fuzzy logic calculations. Validation of the calculation results of fuzzy logic using Takagi-Sugeno method by comparing it with the Tsukamoto method showed differences in the results of the sensor output voltage of solar cells that are not significant (0.001 V), but the Takagi-Sugeno computation is more efficient because it utilizes the incorporation of fuzzy logic calculations with two outputs at once, compared to Tsukamoto methods that performs calculations on the fuzzy output one by one
