Abstract
Buck-Boost Converter adalah suatu DC-DC Converter yang memiliki kemampuan menaikkan dan menurunkan tegangan masukan yang diberikan. Mode buck mewakili kemampuan menurunkan tegangan dan mode boost mewakili kemampuan menaikkan tegangan. Kontrol Logika Fuzzy adalah suatu metode pengontrolan sistem berdasarkan basis aturan (rule based system) yang menggunakan Logika Fuzzy sebagai cara pengambilan keputusan. Aturan dibuat dengan menggunakan inferensi Mamdani dan metode defuzzifikasi weighted average untuk mendapatkan nilai crisp. Dilakukan tiga kategori pangujian yaitu, masukan tetap dan keluaran tetap, masukan tetap dan keluaran bervariasi, dan masukan bervariasi dan keluaran tetap. Hasil yang didapatkan dari penelitian ini: ketika masukan tetap dan keluaran tetap terdapat rerata error steady state 0.744034458% pada keluaran 12V dan tidak ada overshoot maupun undershoot, ketika masukan tetap dan keluaran bervariasi terdapat rerata error steady state 0.098206141% pada keluaran 9V, 0.956200828% pada keluaran 12V dan 0.485500565% pada keluaran 15V dan tidak ada overshoot maupun undershoot, ketika masukan bervariasi dan keluaran tetap terdapat rerata error steady state 0.893472397% pada keluaran 12V, 38.45190654% rerata overshoot dan 25.53735524% rerata undershoot.
English Abstract
In this research, the design and manufacture of a buck-boost converter with fuzzy logic control for solar panel systems was made. The purpose of this research is to make a buck-boost converter with an output voltage stability control system using fuzzy logic control so that it can stabilize the output voltage of the buck-boost converter and can repair external interference. The design of the buck-boost converter includes calculating the value of the inductor, capacitor, and other components used. The control method used in this research is the fuzzy logic method as a control decision making. There are two inputs and one output in the fuzzy logic control used. The input of fuzzy logic control consists of error and delta error. The error is obtained from the result of reducing the setpoint with the voltage reading from the differential amplifier and the delta error is obtained from the result of reducing the error and previous error. Error and delta error can be represented by Negative Big (NB), Negative Small (NS), Zero (Z), Positive Small (PS), and Positive Big (PB). The Mamdani inference method and weighted average for defuzzification were used. The output of fuzzy logic control is delta pwm which is represented by Negative Big (NB), Negative Small (NS), Zero (Z), Positive Small (PS), and Positive Big (PB). Delta pwm is the parameter that will be added to the previous PWM value, the result of the sum will be the PWM value. The results obtained from this research: when the input is fixed and the output fixed, there is an average steady-state error of 0.744034458% at the 12V output and there is no overshoot or undershoot, when the input is fixed and the output varies, there is an average steady-state error of 0.098206141% at 9V output, 0.956200828% at the output is 12V and 0.485500565% at 15V output and there is no overshoot or undershoot, when the input varies and the output fixed, there are an average steady-state error of 0.893472397% at 12V output, 38.45190654% average overshoot and 25.53735524% average undershoot.
