Ansyari, Muhammad Ridho (2019) Pengaturan Tegangan Buck-Boost Converter Menggunakan Logika Fuzzy Sebagai Penalaan Parameter Kendali PID. Sarjana thesis, Universitas Brawijaya.
Abstract
Penggunaan sistem daya DC semakin luas digunakan, seperti sistem photovoltaic (PV) sehingga diperlukan sistem untuk mengkonversi sistem daya DC, salah satunya adalah buck-boost converter. Sistem buck-boost converter tanpa pengendali mampu mengkonversi sistem daya DC, namun hasil konversinya tidak stabil. Diperlukan pengendali agar tegangan keluaran yang dihasilkan sesuai yang diinginkan dan stabil tanpa ada gangguan saat buck-boost beroperasi. Makalah ini mengkaji perbaikan unjuk kerja buck-boost converter dengan menggunakan pengendali PID dan fuzzy-PID. Pengendali PID mampu menghasilkan kepresisian serta kestabilan, sedangkan algoritma fuzzy menunjukkan kinerja yang baik ketika digunakan pada sistem yang tidak linier, disamping mudah diubah-ubah. Pengendali PID dan fuzzy-PID disini mengatur duty pada MOSFET buck-boost converter sehingga nilai keluaran sesuai dengan nilai referensi, selain itu pengendali juga mengatur ketidakstabilan sistem keluaran seperti overshoot, osilasi, dan kecepatan steady state. Pengujian dilakukan pada MATLAB dengan melakukan pemodelan matematika buck-boost terlebih dahulu. Hasil perbandingan simulasi implementasi pengendali PID dan fuzzy-PID memperlihatkan bahwa waktu pemulihan fuzzy-PID lebih cepat dari PID. Dari perbandingan tersebut juga terlihat bahwa jumlah deviasi tegangan fuzzy-PID lebih kecil dari PID. Dapat dikatakan sistem dengan pengendali fuzzy-PID lebih baik dari sistem dengan PID.
English Abstract
The use of DC power systems is increasingly widely used, such as photovoltaic (PV) systems so a system is needed to convert DC power systems, one of them is the buck-boost converter. The buck-boost converter system without controllers is able to convert DC power systems, but the conversion results are not stable. A controller is needed so that the output voltage is as desired and stable without any difficulties when buck-boost is operated. This paper examines the improvement of the performance of the buck-boost converter using PID and fuzzy-PID controllers. PID controller is able to produce precision and stability, while fuzzy algorithms show good performance used in systems that are not linear, besides easily changeable. The PID and fuzzy-PID control here regulates the duty on the MOSFET buck-boost converter so that the approval value is in accordance with the reference value, besides that the controller also regulates the instability of the output system such as overshoot, oscillation, and steady state speed. Testing is done in MATLAB by doing mathematical buck-boost modeling first. The results of a comparison of the simulation of PID controller and fuzzy-PID implementation show that fuzzy-PID recovery time is faster than PID. The comparison also shows that the amount of fuzzy-PID voltage deviation is smaller than PID. It can be said that a system with a fuzzy-PID controller is better than a system with PID.
