Abstract
Energi angin dapat dimanfaatkan untuk menghasilkan energi
listrik, untuk memanfaatkan energi tersebut, salah satu alat yang dapat digunakan adalah turbin angin, dengan faktor kecepatan angin yang bervariasi akan menjadi kendala dalam desain turbin angin tersebut. Faktor tersebut akan mempengaruhi kecepatan putar turbin angin. Dalam tugas akhir ini telah dirancang sebuah sistem pengendalian sudut pitch pada prototipe turbin angin berbasis interval type II fuzzy logic dengan tujuan mendapatkan performansi turbin angin yang optimal. Bilah yang digunakan bertipe non-uniform blade untuk jenis kecepatan angin rendah dan turbin angin berukuran kecil dengan profil penampang airfoil NREL S83n. Pengujian kontrol dilakukan dengan setpoint 10, 15, 20 dan 25 pps. Berdasarkan hasil pengujian didapatkan data rise time dan settling time tercepat sebesar 38 detik dan 29 detik saat setpoint 10, sedangkan yang terlama 140 detik dan 134 detik saat setpoint 25. Maksimum overshoot tertinggi sebesar 10% saat setpoint 10 dan terendah sebesar 0% saat setpoint 25. Error steady state tertinggi sebesar 5,1% saat setpoint 10 dan terendah sebesar 2,06% saat setpoint 15. Nilai ITAE terendah 307 saat setpoint 10, ITAE tertinggi 1787 saat setpoint 25. Sistem pengendalian yang terbaik untuk respon sistem turbin angin ini yaitu saat setpoint 25, karena memiliki error steady yang kecil (dibawah toleransi 5%) dan tidak adanya maksimum overshoot.

Wind energy can be used to generate electrical energy. Wind turbine is one of the instrument that can be used to take benefit of this wind energy, speed variation of the wind will be a factor of consideration in designing wind turbine. That factor will affect the rotational speed of wind turbines. This final project has designed a blade pitch angle control system control for wind turbine prototype based on interval type II fuzzy logic. The aim is to obtain results in form of optimal rotation of wind turbine. Blades used non-uniform type for low wind speeds and small-sized wind turbines with NREL airfoil profile S83n. Setpoint control test carried out with 10, 15, 20 and 25 pps. From the results of the test, it is obtained that : the fastest rise time and settling time at 38 seconds and 29 seconds when setpoint 10, whereas the longest 140 seconds and 134 seconds when setpoint 25. Maximum overshoot peak 10% when setpoint 10 and lowest 0% when setpoint 25. The highest steady state error 5.1% when setpoint 10 and the lowest 2.06% when setpoint 15. The lowest ITAE value 307 when setpoint 10, while the highest value 1787 when setpoint 25. The best control system for wind turbine system response when setpoint 25 pps, because it has small error steady state (under a tolerance of 5 %) and the maximum overshoot is 0%.
