Implementasi Pengendalian Tegangan Keluaran Pembangkit Listrik Tenaga Bayu (PLTB) Skala Piko Menggunakan Cuk Converter Dengan Tuning Fuzzy Logic Control

Abstract

Pico-scale Wind Power Plants have a weakness, its  the wind speed fluctuations that affect the stability of the generator's output voltage. This study aims to design and implement a Cuk Converter device controlled using the Fuzzy Logic Control method to achieve voltage stability at a Set Point of -12.4 V. The control system is designed using an Arduino Mega 2560 microcontroller that processes input data from the sensor in the form of error and delta error. The testing was conducted with an input voltage ranging from 7 V to 15 V and loads ranging from 10 W to 40 W. In the tests conducted, the fuzzy control obtained good results with a rise time of 1.8–2.66 s, a settling time of 2.31–2.96 s, and a low overshoot of 0%–1.61%, along with a steady-state error of 0.56%–1.21%. The designed system is capable of maintaining voltage stability despite changes in the input voltage and load variations within the system.
