Solar Tracker Elektro-Pneumatik Berbasis Kendali Fuzzy
Sari
ABSTRAK
Salah satu faktor yang mempengaruhi daya keluaran listrik dari panel surya adalah posisi dan tingkat penyerapan sinar UV (Ultraviolet) dari matahari. Penggunaan aktuator motor servo untuk solar tracker membebani listrik yang dihasilkan dari pembangkit internal panel surya. Pada penelitian ini dirancang solar tracker menggunakan silinder pneumatik sebagai pengganti aktuator motor servo. Sedangkan, sensor UV digunakan untuk memantau sudut pergerakan matahari. Nilai error dan Δerror dari hasil pengolahan data sensor UV menjadi masukan bagi sistem pengambilan keputusan berbasis kendali fuzzy. Keluaran sistem pengambilan keputusan ini mengatur pergerakan posisi silinder pneumatik naik, turun, atau stop. Pengujian perangkat bekerja dengan baik, menghasilkan respon dinamik overshoot 5,3 % dan error steady state 1,6 %.

ABSTRACT
One of the factors that affect the electrical output power of solar panels is the position and the absorption level of UV (Ultraviolet) rays from the sun. The use of a servo motor actuator for solar trackers burdens the generated electricity from the solar panels internal generator. In this study, a solar tracker was designed using a pneumatic cylinder as a replacement for the servo motor actuator. While a UV sensor was used to monitor the angle of the sun’s movement. The error and Δerror values from UV sensor data processing results become an input for decision-making systems based on fuzzy control. The output of this decision-making system regulates the movement of the position of the pneumatic cylinder up, down, or stopping. The test device worked properly, resulting in a dynamic response overshoot of 5.3% and a steady-state error of 1.6%.
